Types of Hosting There are 4 main types of hosting, depending on your needs, budget, and technical skills: What it is: Multiple websites share the same server and resources. Best for: Beginners, small websites, blogs. Pros: Cheap, easy to use. Cons: Limited performance, less control, security risk from other users. Examples: Hostinger, Bluehost, GoDaddy, Namecheap What it is: A physical server divided into virtual servers. You get dedicated resources. Best for: Developers, small-to-medium apps, testing environments. Pros: More control, better performance than shared. Cons: Needs basic sysadmin knowledge (SSH, Linux, Docker). Examples: DigitalOcean, Linode, Hetzner, Vultr What it is: You get the whole physical server just for your app. Best for: Large apps, enterprise workloads, high-traffic systems. Pros: Full control, top performance. Cons: Expensive, requires advanced knowledge to manage. Examples: OVH, Liquid Web, IBM Cloud Bare Metal What it is: On-demand infrastructure with autoscaling, storage, and other services. Best for: Scalable apps, modern deployments, CI/CD workflows. Pros: Scales easily, pay-as-you-go, supports containers/microservices. Cons: Learning curve, can be costly over time if not optimized. Examples: Cloud providers: AWS (EC2, ECS, Lightsail), Azure, Google Cloud PaaS: Render, Railway, Heroku, Vercel (frontend), Netlify (frontend) Some hosts specialize in Docker/Kubernetes: For Docker Compose: VPS (DigitalOcean, Hetzner) For Kubernetes: AWS EKS, Azure AKS, GCP GKE, or K3s on your VPS If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )

Implementing a JavaScript plugin system using Rust with Deno can be an exciting challenge.

Originally written at pooyan.info Who is the author? Check out my profile on LinkedIn. Vendor lock-in refers to a situation where an organization becomes overly dependent on a specific vendor's products or services, making switching to alternatives costly, time-consuming, or technically difficult. Over the years, many companies have experienced frustration when trying to move away from large vendors like IBM, Microsoft, or Oracle due to contractual constraints, proprietary technologies, and sudden pricing changes. A recent example is VMware's acquisition by Broadcom, followed by significant pricing changes that disrupted many businesses.

Introduction If you’ve ever encountered the no main manifest attribute error while trying to run a JAR file in Java, you’re not alone. This common issue arises when the JAR file lacks the necessary metadata to specify the entry point of your application. This article will guide you through understanding this error, configuring your pom.xml file correctly, and successfully packaging your Java application into a runnable JAR file. Understanding the Error When you package a Java application into a JAR file, the Java Runtime Environment (JRE) looks for a specific entry in the JAR's manifest file to understand where the main class is located. If this entry is missing, Java throws the no main manifest attribute error. This typically happens when the maven-jar-plugin isn't correctly configured in…  ( 5 min )

Leapcell: The Best of Serverless Web Hosting The Python code style guide is not set in stone. It evolves continuously with the development of the language. Some old conventions are gradually phased out, and new ones keep emerging. At the same time, many projects have their own coding style guides. When there are conflicts, the project-specific guides should be followed first. However, there is an important principle to keep in mind: "The stupid persistence in consistency is the monster of ignorance", which is a profound insight from Guido. Since code is often read more frequently than it is written, the core goal of the style guide is to improve code readability and keep all kinds of Python code consistent. As PEP20 says, "Readability counts". The style guide emphasizes consistency. While …  ( 10 min )

Today I need to find a suitable foundational library for video processing. FFMpegCore works for one-shot things but despite a fluent API, its interface is still too command line like. Here is what I found out: OpenCvSharp LibVLCSharp FFMediaToolkit Frames ✅ decode / encode ✅ (via callbacks) ❓ Audio ❌ ✅ decode / encode / mux ❓ Extra libs ~5 MB/platform +7 MB +7 MB Licence Apache‑2.0 LGPLv2.1 MIT Platforms Win / mac / Linux / Arm Win / mac / Linux / iOS / Android Win / mac / Linux LibVLCSharp seems more focused on directly displaying things (e.g. in Xamarine and WPF) instead of low-level API based processing; FFMediaToolkit, on the other hand, still depends on FFMPEG and can't avoid licensing issue. Eventually, I had to go with separate video + audio processing in favor of OpenCvSharp (it's Apache-2.0 by the way). Notice OpenCVSharp has some advantage over EmguCV for custom dev: OpenCvSharp Emgu.CV Licence Apache-2.0 (fully permissive) GPL v3 or commercial licence Interop model Pure P/Invoke (no C++/CLI), works on any .NET core runtime Historically C++/CLI wrapper (needs Windows for full feature set), .NET Standard P/Invoke layer added later NuGet size (native) 4–6 MB per RID (modular runtime packages) 30 MB + for the “opencv‑world” monolith, or 90 MB for emgucv‑runtime‑ubuntu GPU (CUDA) support Provided in separate OpenCvSharp4.runtime.dnn package Official CUDA builds, but Windows‑only binaries unless you compile yourself API surface ~1:1 with OpenCV C++ names (easy to port C++ samples) Thicker .NET façade (e.g. Image types), extra helpers Cross‑platform stability Actively tested on Windows / Linux / macOS / arm64 Windows the main focus; Linux/macOS possible with libopencv from distro or big runtime package Learning curve If you know OpenCV C++ you feel at home Higher‑level abstractions can be friendlier for newcomers Commercial support Community‑driven Paid licences & support available from Emgu CV, Inc.  ( 3 min )

Semicolons were often added to the end of URLs, especially in r/Conservative summaries, and they became a part of the hyperlinks wrongly, making some of the hyperlinks unusable. I often randomly test the hyperlinks and they all worked, but I just realize that I only test the longest hyperlinks, because I think they are the ones more prone to hallucinations. I didn't find any hallucinations. But yesterday I clicked some of the simpler links of r/Conservative summaries and I got 30% of them not working. I panicked because I thought the hallucination caught me off guard, but then I realized all the links were real, but they each got an additional ";" attached to them, which was redundant. The links themselves were correct but the semicolons I used to declare the end of line was wrongly identified as part of the URLs. The fix was simple. I removed all redundant semicolons from all my current and previous output documents. I am really surprised of this bug because it affected so many links but it evaded my "random" sampling for so long, because I didn't test the rendered URL links very thoroughly, and I thought very long and complex links were at higher risks of hallucination, so I tested those a lot. Weird enough, those never had problems, but the shorter, simpler links did. I am very sorry for the potential confusion it might have created.  ( 3 min )

This distribution also serves as a meaningful way to thank our earliest supporters and introduce them to USD1,” the proposal states.  “This will allow World Liberty Financial to validate the technical functionality of its airdrop system in a live environmen…

Coinbase has introduced a new payments protocol for online payments that enables stablecoin transfers over standard internet protocols and AI agents to transact autonomously.   On May 6, Coinbase announced that it is launching a protocol called x402 for instant stablecoin payments directly over the internet communication protocol HTTP (Hypertext Transfer Protocol). It allows Application Programming Interface (APIs), apps, and AI agents to transact seamlessly, “unlocking a faster, automated internet economy,” the firm stated.  Coinbase said that x402 “is fixing the internet’s first mistake.” The protocol resurrects the experimental HTTP 402 “Payment Required” status code to create a seamless payment system native to the internet. The firm noted that traditional payment rails, such as credit…

Key takeaways: Bitcoin must maintain above $95,000 to have a chance at retesting its $109,000 all-time high; failure to hold could lead to a deeper correction, crypto analysts warn. Several crypto analysts told Cointelegraph in March that Bitcoin may have a chance of reaching new all-time highs in June. The upcoming Federal Reserve decision on May 7 could influence Bitcoin’s price movement over the coming days. Bitcoin needs to continue to hold above the $95,000 level for a chance to climb back and retest its all-time high, or face an even deeper correction, crypto analysts say. It comes after several analysts told Cointelegraph earlier this year that June could be the month Bitcoin (BTC) reaches new all-time highs. “The $95,000 level — currently under consolidation — is a critical piv…

Members of the crypto community are circulating apparent “proof” that Zerebro developer Jeffy Yu faked his suicide as he promoted his new memecoin during a Pump.fun livestream on May 4. The belief appears to come from an unverified private letter supposedly sent by Yu to a Zerebro investor, trading activity linked to crypto wallets owned by Yu, and the removal of his obituary from Legacy.com. Others speculate that Yu used a tool to pass off a pre-edited video as if it were filmed in real-time during the Pump.fun livestream. Source: Hash The unverified letter from Yu to an early investor states that he deliberately created a livestream pretending to shoot himself as it was the only “viable exit” from persistent harassment, blackmail, threats and hate crimes. “Being fully doxxed has placed m…

US Democrat lawmakers have launched a multi-angle attack on President Donald Trump’s crypto ventures with two bills and a subcommittee inquiry aimed at cutting his ability to profit from the initiatives.    The Modern Emoluments and Malfeasance Enforcement Act, or the MEME Act, aims to prevent federal officials from using their position to profit from memecoins, Democrat Senator Chris Murphy said in a May 6 statement.  If passed, the MEME Act prohibits the president, vice president, members of Congress, senior executive branch officials, their spouses and children from issuing, sponsoring, or promoting a security, future, commodity, or digital asset, according to the bill’s description.  Today I’m introducing a bill - the MEME Act - to ban a President or Member of Congress from issuing a …

The relationship between Gross Domestic Product (GDP) and stock market performance is a subject of considerable interest to economists, investors, and policy makers alike. GDP measures the total value of goods and services produced by a country, and it serves as an indicator of the health and growth of an economy. The stock market, on the other hand, reflects the collective value of publicly traded companies and serves as a platform for buying and selling shares. Both metrics are often used to gauge economic conditions, yet their relationship is more complex than a simple correlation. While there is a connection between GDP growth and stock market performance, this relationship is influenced by various factors, including investor sentiment, economic policies, and external events. In some c…  ( 7 min )

In this blog post, I'll walk through how I built a simple Agent-to-Agent (A2A) math service using Python. The A2A protocol is Google's initiative to standardize how AI agents communicate with each other, creating an interoperable ecosystem of specialized AI services. The Agent-to-Agent (A2A) protocol is designed to enable AI agents to communicate with each other using a standardized messaging format.

There was a time when software releases were slow and monolithic—but at least everything was in one place. Now, we move faster. But that speed? It comes at a cost. Today, we live in a world of microservices, APIs, and distributed everything. The architecture is elegant. The orchestration is powerful. But testing? That’s where things get tricky. As a quality engineering leader, I’ve seen firsthand how this complexity tests more than just code—it tests our assumptions about ownership, accountability, and what “done” really means. In a microservices ecosystem, a single user journey might hit a dozen services. Each is built, deployed, and owned by a different team. And while unit tests may pass with flying colors, it’s the integration points—those fragile handshakes between services—that often…  ( 4 min )

Introduction In Java, managing complex key structures dynamically is a common challenge, especially when dealing with API response times and performance issues. In your scenario, you're saving keys in a map formatted like Krishna/thota/date/x/y/z while supporting wildcard characters (*) to match various entries. However, this approach leads to performance overhead due to the necessity of comparing strings, which can be inefficient when handling over a million records. We’ll explore better data structures and solutions to enhance performance while allowing for the flexibility you need for matching. Understanding the Performance Issue You mentioned that your current implementation takes approximately 200 milliseconds when you have more than one million records. This degree of latency can aff…  ( 5 min )

When a small purple dragon leapt joyfully onto television screens in 1998, gaming felt simpler. Spyro's tale was charmingly clear-cut: dragons good, Gnorcs bad. Yet, as those early fans grew alongside the medium itself, uncomplicated childhood memories gave way to reflective curiosity. With maturity comes the realisation that even playful narratives can unwittingly reveal complex truths—sometimes challenging, always intriguing. Among Spyro's cast, no group invites this reconsideration quite like the Gnorcs. Originally depicted as brutish, green-skinned adversaries to vanquish without second thought, today they stir conversation far beyond simple nostalgia. Central to this renewed interrogation of Spyro's world is Gnasty Gnorc himself. Once an outright villain, his motivations now appear le…  ( 6 min )

Most teams spend hours documenting everything. Notion workspaces. Confluence pages. GitHub wikis. You name it. But here’s what happens: ☑️New hires still get stuck. ☑️Devs still ask questions that are, “Somewhere in the docs” and crucial context gets lost. This is the Documentation Paradox: The more you write, the harder it gets to find, trust, and maintain what actually matters. Conventional wisdom says, “Async teams need tons of docs!” But I’ll say: More docs often mean less clarity. Here’s why: First, there's the maintenance burden. Every line of documentation is a liability that needs updating as your codebase evolves. How many teams actually do that? Second, comprehensive documentation creates a false sense of security. Teams believe they're covered because it's in the docs somewhere. What you should do is treat documentation as a conversation, not an artifact. Use tools that make updating docs as easy as sending a message. Encourage annotations and questions directly in the documentation. And remember the 20/80 rule: 20% of your features generate 80% of questions. Focus your efforts there. The goal isn't to have everything documented – it's to have the right documentation that actually helps your team move faster. This is why every Rally session lives forever inside Jira No more sorting through old Slack threads. Every discussion stays tied to the task, so your team’s knowledge grows with the work—not in a dusty folder.  ( 3 min )

In C#, there isn't a built-in method equivalent to Ruby's humanize for turning strings into a more natural format, but you can create functions to achieve this easily. In this article, we'll explore how to convert strings while following the two scenarios provided in your request: changing capitalization and formatting string cases to appear more human-friendly. Understanding the Humanization Process When we discuss 'humanizing' a string, we're typically referring to text transformation that makes it easier for humans to read or understand. This can involve adjusting capitalization, changing the case, or formatting text to look more polished and readable. Unlike Ruby, where the humanize function applies well-defined transformations, C# requires us to craft our own methods. Implementing a S…  ( 4 min )

Introduction When working with Rust and Diesel, you may encounter various issues, especially when performing count queries. In this article, we'll examine a specific error that arises from executing a count query using Diesel with PostgreSQL. The error message states, 'the trait bound i32: FromSql is not satisfied'. This indicates a type mismatch in your query resolution. Understanding the Error The error is primarily triggered because the Diesel ORM expects a specific data type from the SQL count result. Typically, when using the count function in a SQL query, the result is of type BigInt in PostgreSQL, which corresponds to i64 in Rust. However, your code attempts to return the result as an i32, leading to the compile error. Step-by-Step Solution Changing Return Type to i64 Th…  ( 4 min )

When working with CodeIgniter, you might want to utilize its query builder feature for better performance and security. For instance, let's consider the SQL query: SELECT * FROM questions WHERE course_id = 13; This query retrieves all records from the 'questions' table where the course_id is equal to 13. However, using raw SQL queries in CodeIgniter, as shown below, can lead to issues: $query2 = $this->db->query('SELECT * FROM questions WHERE course_id = 13', false); Why is This Query Problematic? Using this method can lead to potential SQL injection vulnerabilities, and it's not as efficient as using the CodeIgniter Query Builder. Additionally, the parameters need to be validated or sanitized especially when you’re dealing with user input. Using the Query Builder in CodeIgniter The Code…  ( 4 min )

Sightful’s Spacetop for Windows is a $899 bundle (plus a $200/yr subscription after year one) that turns your compatible Intel-powered laptop and Xreal Air 2 Ultra smart glasses into a multi-monitor, spatial-computing workspace. Wired gave it a 9/10, praising its polished software, comfy glasses (with dimming for outdoor use) and the private, ultra-portable productivity it delivers—arguably edging out Apple’s Vision Pro at a fraction of the price. It’s not all sunshine, though: the setup looks a bit dorky, only works on select Intel CPUs for now, saps battery life in a hurry and the glasses’ field of view could be wider. Still, if you’ve been dreaming of carrying your home-office everywhere, Spacetop might finally make it happen.  ( 3 min )

Greetings to all! In this article, we will talk about a rather unusual topic, information about which for some reason I did not find, although it is quite useful in modern JavaScript frameworks and libraries for creating user interfaces, because, in some cases, applying the concept can help speed up work with the DOM several times. The name is conditional, but the essence is important. The term "usual state" refers to data that is saved directly due to the state managers, or due to the internal functionality of the framework or library.

Dissecting the HTTP Request — Line by Line Demystifying HTTP for Web Developers, Part 2 In Part 1 of this series, we traced the full journey of an HTTP request — from typing a URL in the browser, through DNS resolution and TCP handshakes, all the way to receiving the server’s response. But understanding the path a request travels is only half the story. To truly master HTTP, we now need to dissect the payload that actually moves across the wire: the HTTP request itself. Every interaction between a web client and a server begins with a carefully structured message — the request. It may look simple on the surface, but every line, header, and byte in that request carries meaning. If you’re building serious web applications, APIs, or even debugging flaky integrations, you can’t a…  ( 13 min )

In this post, I test how Mistral's Codestral, the model specifically trained to generate code, compares to the Mistral's Le Chat, the general AI chat. For my experiment, I use the Royal Game of Ur, an ancient Babylonian game that I already implemented using Le Chat. At least in my experiment, Codestral's performance is, frankly, disappointing. While it produces code that follows a certain architecture, the code quality is low. In fact, it even generates a statement of the form a = foo() where a has a different type from what foo() returns. Read on for more details. After the same prompt as with Le Chat, Codestral's response is: To implement the Royal Game of Ur in Python, we need to define several components: Game Board: Represent the board and the special squares.

Everyone’s in the cloud. Stacks have migrated. Infrastructure is containerized. CI/CD pipelines are green. But behind the wave of “cloudification”, one question lingers: Have we really changed the way we think? Because on the surface, everything looks modern. But underneath? ⏱️ Services running 24/7 💤 Containers sitting idle, waiting for traffic that never comes 💸 Bills growing, even when no one clicks “deploy” And in every retro, every finance meeting, the same old line: “The cloud is expensive.” But is it really the cloud that’s expensive? Or is it… The quiet luxury of feeding CPUs that are just bored? Let’s be honest. Cloud-native isn’t Docker. It’s not Kubernetes. It’s not Terraform, or some magic mix of YAML, containers, and CI/CD. Those are tools. Powerful ones. But tools. Clo…  ( 5 min )

Introduction: So You Want Your LLM to Stop Guessing Everyone’s buzzing about Retrieval-Augmented Generation (RAG) like it’s the second coming of AI engineering. And honestly? It kinda is. Your large language model is excellent at confidently making things up—because it doesn’t actually know anything beyond whatever data it was last trained on (hello, 2023). That’s where RAG comes in: bolting on real, external knowledge so your LLM stops hallucinating and starts reasoning. But here’s the thing: knowledge isn’t just about facts. It’s about how things connect. And when relationships matter, you don’t want a flat file or a relational torture device. You want a graph. Enter the graph database.

In the first and second parts, we focused on creating two different patterns for handling data flow in React. EventTarget is the foundation of the browser’s event system. addEventListener, removeEventListener, and dispatchEvent. Many core Web APIs including DOM elements like , , , as well as document and window inherit from EventTarget. When we attach an event handler to a DOM element—like in the picture above—we’re actually subscribing to that element through one of its event channels. In this case: The button is the publisher (or emitter) The callback function passed to addEventListener is the subscriber (or listener) So when a user clicks the button, the button emits a 'click' event, and all registered listeners for that event type are notified and executed. So with…  ( 5 min )

I’m a product owner, guiding a team building a collaboration app for remote workers. Last quarter, we rushed a feature—real-time document editing—without thorough testing.

If you go back to the first talk ever given on webhooks, it opens on the command-line. Specifically the Unix shell, focusing on one of its defining features: pipes. The idea was that pipes brought a new level of compositionality to programs, and webhooks could bring a new level of compositionality to web apps. Perhaps you could say I was trying to bring the spirit of Unix to the web. With this last release of Wanix, I'm at it again. This time with the successor to Unix, a little known operating system called Plan 9 from Bell Labs. Plan 9 has been on my mind for quite a while. In fact, around the time of that first talk on webhooks, the team behind Unix and Plan 9 was being re-assembled to create the Go programming language.

O que é o Padrão Decorator? O Decorator é um padrão de projeto estrutural que permite adicionar comportamentos adicionais a um objeto de forma dinâmica. Ele permite que você encadeie funcionalidades (como validação, construção, logging e outras) em um fluxo sequencial, sem modificar a estrutura original da classe. Isso possibilita adicionar ou remover comportamentos com facilidade, mantendo o código mais flexível e desacoplado. Em resumo, o Decorator cria uma cadeia de responsabilidades onde cada classe pode adicionar sua funcionalidade à sequência, sem afetar as outras. Imagina que você precisa realizar várias validações (como validar o usuário, estoque e status), mas não quer que elas fiquem fortemente acopladas. O objetivo é poder adicionar, remover ou reorganizar facilmente as valida…  ( 4 min )

TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}' TypeScript has quickly become a favorite tool for developers building scalable and maintainable JavaScript applications. At its core, TypeScript is a superset of JavaScript—it builds upon JavaScript by introducing static typing, as well as other modern programming concepts that make your code safer and easier to manage. Static typing means that developers can explicitly define the types of data (like string, number, or boolean) their variables and functions work with, catching potential errors during development instead of at runtime. If you're new to TypeScript, or want to sharpen your existing skills, consider following our blog or using advanced learning tools like gpteach.us to explore how modern AI tools ca…  ( 6 min )

TS2333: 'this' cannot be referenced in constructor arguments TypeScript is a statically-typed superset of JavaScript designed to add type safety and developer-friendly features to JavaScript code. A "superset" means that TypeScript builds on JavaScript by adding new functionalities, while still allowing you to write plain JavaScript. One of its most powerful features is the introduction of types (a system to define constraints on the structure of your data). This is immensely beneficial when working in large projects to detect errors at compile time, ensuring your codebase is reliable and maintainable. Types in TypeScript help us describe the shape of an object, function, or data. For instance, when you define a function or an object, you can explicitly specify what inputs it expects and…  ( 6 min )

TS2332: 'this' cannot be referenced in current location TypeScript is a popular open-source programming language developed by Microsoft. It’s often referred to as a superset of JavaScript because it builds on JavaScript by adding optional static types. These types allow developers to define the structure and behavior of variables, functions, and objects, making programs easier to debug and maintain. TypeScript compiles to plain JavaScript for execution, which means it seamlessly integrates with existing JavaScript projects. Simply put, types in TypeScript are what allow you to specify the kind of data a variable or function should handle. For instance, you can declare that a variable must always hold a number, a string, or a custom structure (like objects or classes). By catching errors …  ( 6 min )

TS2331: 'this' cannot be referenced in a module or namespace body TypeScript is a powerful language that builds upon JavaScript by adding optional static typing. By introducing "types" (representations of data such as strings, numbers, and objects, among others), TypeScript allows developers to write more predictable and maintainable code. It’s often referred to as a superset (a language that extends the features of another) of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. A major advantage of TypeScript is its ability to catch errors during development, before the code is executed. However, while it enhances safety and boosts productivity, developers may sometimes encounter compiler errors that seem confusing at first. One such error is TS2331: 'this' ca…  ( 5 min )

TS2329: Index signature for type '{0}' is missing in type '{1}' TypeScript is a strongly typed superset of JavaScript. This means that it builds on top of JavaScript by adding an optional type system (a way to define and enforce the kinds of data being used in your code). TypeScript is a powerful language designed to catch errors early during development, making your JavaScript codebases more robust and maintainable. In TypeScript, "types" play a central role. A type defines the shape of data, specifying what kind of data will be stored, its expected structure, and the operations you can perform on it. For example, string, number, boolean, and object are common types used in TypeScript. Types ensure that your code only operates on the data it was designed to handle; if it doesn’t match t…  ( 6 min )

TS1433: Decorators may not be applied to 'this' parameters TypeScript is a strongly-typed programming language that builds on JavaScript by adding static types (data classifications, such as string or number). TypeScript helps developers write safer, more predictable code because it allows the compiler to catch potential bugs during the development process, before the code is executed. Essentially, TypeScript acts as a typed superset of JavaScript, meaning it includes all the features of JavaScript while adding new functionalities, mainly focused on type safety.

Tokenization refers to the process of converting ownership of an asset, such as stocks, real estate, or artwork, into a digital token on a blockchain. This token represents ownership or a portion of ownership of the underlying asset. In the case of U.S. equities, tokenization means turning traditional company shares into digital tokens that are recorded on a blockchain ledger. Blockcha…  ( 8 min )

How I built VidSabio.com by combining multiple LLMs into a robust processing pipeline I recently launched VidSabio, a platform that transforms ordinary videos into structured, interactive learning experiences — automatically. 🎥➡️📚 But this didn’t come together overnight. At first, I thought a single LLM could handle everything: analyze the video, transcribe it, generate quizzes, build a course. Easy, right? Wrong. It turned out the real breakthrough came when I stopped looking for one model to do it all — and instead built a pipeline of specialized steps, each powered by the best tool for that specific task. Here’s the high-level breakdown of how it works: User uploads a video Video is processed through a multi-step pipeline: Frame extraction (FFmpeg) Audio transcription (Google Speech-to-Text) Visual analysis (Gemini / GPT-4 Vision) Content summarization + topic generation (Gemini Pro) Course structure generation (GPT-4) Interactivity injection (quizzes, accordions, etc.) Final course can be edited and exported as SCORM or HTML This is all built using Vue 3, Firebase, and various LLMs (OpenAI + Gemini) stitched together through Cloud Functions. By distributing the heavy lifting across multiple LLMs and APIs, I was able to: Improve accuracy Scale more efficiently Debug and retry isolated steps Customize outputs based on step-level feedback Frontend: Vue 3 + Tailwind Backend: Firebase Functions + Firestore + Storage AI: GPT-4.1, Gemini Pro, Whisper, Google Speech-to-Text Analytics: PostHog Export: SCORM, HTML Here's a stylized diagram of the flow: (Insert your HappyAlien-styled image here) This was built with plenty of detours, dead ends, and "aha" moments. If you're building with LLMs, I encourage you to explore multi-model orchestration — it might be the key to your next breakthrough.

You’ve been forced to maintain a poorly written legacy app. Spaghetti code, no tests, and every new feature breaks two existing ones. Team morale is at rock bottom. New features take forever to ship. Regression bugs are constant. You gather your arguments and head to management. You: We need time to refactor. Management: What are you talking about? You: Let us refactor. We’ll ship faster, with fewer bugs, and engineers won’t want to quit. I can do it. Management: ...Okay. Now comes the hard part. Are you going to deliver on your promises? Or end up behind schedule and still stuck with a spaghetti codebase? While large-scale refactoring depends on many factors like team alignment, technical constraints, and timing; there’s one powerful technique I’ve used successfully in production to de…  ( 8 min )

If you’ve started learning JavaScript, you’ve probably worked with arrays — those magical lists that hold multiple values. But knowing how to use arrays effectively means understanding the array functions that JavaScript gives us. Let’s break down the most powerful and commonly used array functions that every developer should know. An array is a special variable in JavaScript that can hold more than one value at a time: const fruits = ['apple', 'banana', 'cherry']; .push() – Add to the End fruits.push('mango'); console.log(fruits); // ['apple', 'banana', 'cherry', 'mango'] .pop() – Remove from the End fruits.pop(); console.log(fruits); // ['apple', 'banana', 'cherry'] .shift() – Remove from the Start fruits.shift(); console.log(fruits); // ['banana', 'cherry'] .unshift()…  ( 4 min )

When working with APIs, we often encounter data in formats that do not match our application's preferred coding style. For instance, if you're using TypeScript and Vue.js, you might receive data in snake_case from an API but prefer to work with camelCase throughout your application. The good news is that you can easily transform this data without losing type safety. Let's delve into how you can achieve that with the help of interfaces and utility types in TypeScript. Understanding the Problem When you define an interface such as MergedReviewDetails, you structure your data according to your application's needs. An example of this could be: export interface MergedReviewDetails { parentReview: Mmcid; childReviews: Mmcid[]; } However, the API might return data with properties in snake_ca…  ( 4 min )

In the world of corporate security, not all breaches involve sophisticated hacking tools—some simply walk through the front door. Tailgating, a subtle yet dangerous form of intrusion, happens when an unauthorized person gains access to a restricted area by following closely behind someone who is authorized. It's a tactic that relies less on technology and more on exploiting human behavior. Attackers often masquerade as employees, contractors, or delivery workers. They may carry packages, wear uniforms, or claim to have forgotten their access badge—all to lower suspicion. Once inside, these individuals can do far more than just roam the premises. They might access critical systems, plant malicious software, or steal sensitive equipment. Pretending to be a colleague and asking someone to hol…  ( 4 min )

It was a regular evening debug session. My code was working, but something about it just felt off. I was looping over a list—like always. for i in range(len(my_list)): value = my_list[i] # Do something with value and i Nothing wrong, right? Except... I was starting to hate reading my own code. range(len(...)). Too much manual indexing. 👀 The Realization for i, value in enumerate(my_list): # Do something with i and value Wait... what? No range(len(...))? No messy indexing? ✅ Cleaner 🧠 Why it works: enumerate() is a built-in Python function that returns both the index and the value of items in an iterable—in one shot. It’s like your loop suddenly gained superpowers. 💡 Bonus Tip: for i, val in enumerate(my_list, start=1): print(f"Item {i}: {val}") Perfect for user-facing counters. No more +1 hacks. 🚫 Never Again... No more range(len(...)) unless I really need it. Now, it’s all enumerate(), all day. ✨ Moral of the Story: If you're reaching for range(len(...)), stop and ask yourself— What would enumerate() do? 😎  ( 3 min )

When working with Lumerical FDTD simulations, access to specific fields from the results of a far-field projection monitor might sometimes be challenging, especially when it comes to field names with spaces. In your case, you're able to access standard fields like E2 and Es easily: farfield = getresult("monitor", "farfield"); E2 = farfield.E2; Es = farfield.Es; However, when it comes to the field "Ep vs angle", an error arises. This can happen due to the space in the field name, making direct access using dot notation invalid. Understanding the Structure of the Farfield Object The farfield object typically contains several fields, including E2, Es, and multiple arrays or matrices concerning angles and wavelengths. The fields you can access directly using dot notation are designed to be id…  ( 4 min )

About I was writing a program in go, where I was calling a function,which takes an existing slice, modifies it and returns it back.Then I had a print statement that prints that slice. did not assign the return value of the function call,which is the modified slice,to the old slice variable.In Rust or in some other languages,the compiler will yell at us if we leave the return values of a function call without assigning them. go compiler will not give an error if we leave return values of a function call. So, always look for the function signature before calling the function.  ( 3 min )

In November 2023, the internet trembled when OpenAI’s leadership imploded. Overnight, one of the most powerful AI systems in the world—ChatGPT—was at the mercy of a centralized boardroom battle.

Functions are the heart of any programming language, and in TypeScript, they become even more powerful with type safety. In my latest video, I walk you through how to write and use functions in TypeScript. Whether you're transitioning from JavaScript or just getting started with TS, this tutorial is designed to help you build a solid foundation. 📺 Watch the full tutorial on YouTube: 🚀 What You'll Learn: ✅ Declaring functions with TypeScript ✅ Arrow functions vs traditional functions ✅ Typing function parameters and return values ✅ Optional and default parameters ✅ Clean code and best practices JavaScript is flexible — sometimes too flexible. TypeScript introduces structure by enforcing types, reducing bugs and making your code easier to understand and maintain. With TypeScript, functions can clearly define: What kind of arguments they accept What type of result they return Whether certain parameters are required or optional Here’s a quick example: function greet(name: string = "Dev"): string { return `Hello, ${name}!`; } ` This function: Takes a name parameter of type string Has a default value ("Dev") Returns a string And TypeScript will enforce all of that at compile-time! Real-life function examples Why arrow functions behave differently (especially with this) Tips for writing scalable functions in a TypeScript project `txt ` This video is part of my ongoing TypeScript series. If you're serious about becoming a better web developer, learning TypeScript is non-negotiable.

RDMA(Remote Direct Memory Access)는 네트워크를 통해 서버 간에 CPU 개입 없이 메모리를 직접 읽고 쓰는 기술이다. 주로 고성능 컴퓨팅(HPC), 대규모 데이터 처리, AI/ML 분산 학습 환경 등에서 낮은 지연 시간과 높은 대역폭을 제공하기 때문에 많이 사용한다. 1. RDMA의 기본 개념 일반적인 네트워크 통신 방식에서는 데이터를 전송하려면 CPU가 메모리에서 데이터를 읽고, 네트워크 인터페이스 카드(NIC)로 복사한다. 이 복사한 데이터를 네트워크를 통해 데이터를 보내고, 수신 측에서도 CPU가 데이터를 NIC에서 메모리로 복사한다. 이 과정에서 CPU, 커널, 복사 작업 등이 개입되어 지연(latency)과 CPU 오버헤드가 큰 현상이 발생한다. 반면, RDMA는, CPU나 운영체제(OS) 커널의 개입 없이, 원격 시스템의 메모리에 직접 읽기(read) 또는 쓰기(write) 작업을 수행한다. 다시 말해, 데이터가 직접 메모리에서 메모리로 이동한다. 2. RDMA가 동작하는 방식 (1) 메모리 등록 (Memory Registration) 송신자와 수신자 모두 RDMA NIC(HCA: Host Channel Adapter)를 사용함. RDMA를 사용하기 위해서는 사용할 메모리 영역을 등록(pinning)해야 함. 이 과정에서 해당 메모리는 물리 메모리에 고정되고 커널이 RDMA NIC에 메모리 주소를 알려줌. (2) Queue Pair 생성 RDMA 통신은 QP(Queue Pair)라는 구조를 통해 이루어짐. QP는 Send Queue와 Receive Queue로 구성…  ( 4 min )

The Scraper: The Collector of Car Parts Each day, the Scraper ventured out, gathering essential tools—brake pads, spark plugs, and oil filters—meticulously putting them in his storage room. This storage room, filled with parts, was like a database, organizing all the precious data he gathered from various sources. For instance, one day, the Scraper found a batch of brake pads. He cataloged the details, from brand to condition, and stored it safely. This was like collecting the latest prices from websites, storing them in a file for future use. The Backend Guy: The Toolbox Handler Whenever the mechanic—the Frontend—needed a specific tool, they would call out, “I need a 10mm wrench!” The Backend Guy, standing by the toolbox, would find the correct tool and hand it over with precision. He didn't fix the car himself, but he made sure the mechanic had exactly what was needed at the right time. Just like that, the Backend Guy managed the storage of all the data and ensured it was always ready when the Frontend needed it. When the mechanic asked for the current price of the Euro in Toman, the Backend would retrieve that data and send it in a neat package—a JSON response—ready to be used. The Frontend Mechanic: The User Interface When the mechanic needed a part, they'd shout, "I need a 10mm wrench!" The Backend Guy would respond, handing over the tool, and the Frontend Mechanic would get to work. The mechanic didn’t care how the part got there, as long as it was the right one. In the same way, the Frontend Mechanic used the data provided by the Backend to create an amazing display for the car's dashboard. They made sure the car (or website) looked stunning, with neatly organized parts (like the prices) and a smooth-running engine (user interface). Whether it was showing prices in a nice table or providing a simple, user-friendly experience, the Frontend Mechanic made sure everything was visually appealing and functional.  ( 4 min )

Infrastructure as Code (IaC) has come a long way since its beginnings. What started as spinning up cloud resources has now grown into a full-blown ecosystem with a very engaged community. IaC on its own can add a lot of complexity to your processes and cause more issues, but combined with governance, compliance, security, deployment strategies, self-service, it easily becomes the fuel your delivery engine needs. This year, IaCConf debuts as a virtual event by bringing together this community, and it’s shaping up to be one of the most relevant and practical events in the space. Unlike broader DevOps/SRE or cloud-native events, IACConf is focused on the challenges and innovations around defining infrastructure as code. That means the content goes deeper, the conversations are more relevant, and the takeaways are directly applicable to your processes. There will be sessions on: Getting started with IaC Managing IaC at scale across teams and environments (using OpenTofu, Terraform, Ansible, Crossplane, and others) Platform Engineering and IaC How IaC impacts your maturity AI in IaC And that’s just scratching the surface. Check out the full agenda here. One of the things I appreciate most about this conference is that it’s not about product pitches or high-level fluff. Practitioners share what worked, what broke, and how they improved. Whether you are just starting out, are in the trenches, or shaping platform strategy, there’s something for you here. On another note, I’m also excited to contribute to this year’s lineup with a session on Getting Started with IaC, together with my colleague Emin Alemdar. But honestly, I’m just as excited to learn and to connect with others working through the same challenges. The event will be on Thu, May 15, 2025 @ 11:00am EDT, so don’t forget to register here.

In Rust, understanding how std::mem::transmute functions between different types is crucial for ensuring memory safety and type integrity. This brings us to an interesting question: Is it safe to transmute between two custom struct types, OuterA and OuterB, which only differ by their inner types — InnerA and InnerB? Let's explore what the repr(transparent) conveys and clarify the implications of transmuting types in Rust. Understanding repr(transparent) The #[repr(transparent)] attribute in Rust is used to indicate that a struct represents a single variant of a type that can be safely treated as equivalent to its single field. This is particularly useful for effectively working with opaque types or for implementing newtype patterns. In the provided example, we have the following structur…  ( 4 min )

Introduction When developing Angular applications, particularly with Angular Material, you might encounter issues regarding the mat-list and mat-divider components. Many developers wonder whether to use ngFor inside the mat-list or the mat-list-item and how to correctly place the mat-divider. Let’s delve into this topic to clarify which method is best. Why This Issue Arises The confusion around where to implement ngFor and the positioning of mat-divider often stems from how Angular handles component rendering. Using ngFor within the mat-list means that each item is rendered as part of the list itself; thus, the dividers are less likely to show correctly if their placement isn’t considered carefully. Conversely, applying ngFor to mat-list-item makes each list item independent and potentiall…  ( 4 min )

A proxy firewall, often referred to as an application-layer or gateway firewall, acts as an intermediary between a user’s system and external servers. Instead of allowing direct communication, it processes and forwards requests on behalf of users. This not only hides internal network details from outsiders but also allows the firewall to thoroughly inspect data before it reaches its destination. Unlike traditional firewalls that operate primarily at the network or transport layer, proxy firewalls operate at the application layer. They intercept requests, evaluate the content, and relay approved traffic. This additional layer of inspection allows for more granular control, helping detect threats embedded in seemingly legitimate requests—such as malware hidden in web traffic or email attachm…  ( 4 min )

Hello, I have an ambitious technical idea that I hope to share with the community of developers and cybersecurity specialists: Given the widespread prevalence of pornographic content online, and the difficulty of controlling it through traditional blocking or weak censorship tools, I've come up with a new system: 🔐 An "ethical operating system" (for smart devices – such as Android, iOS, and Windows) built from the ground up on the principle of: "Completely blocking any type of pornographic content, whether visual or textual, whether on websites, apps, search engines, or social networks." 💡 Key features of the idea: Its protection cannot be hacked or changed (such as the inability to install an alternative system). It can be installed on children's devices, school devices, or even the devices of adults who want to protect themselves. It doesn't rely solely on blocking a specific site, but rather on real-time content analysis. A clean app store and a clean built-in search engine. 🧱 Technically: Or as a distribution for children, schools, or conservative environments. Or even as a layer of security added to existing systems (e.g., Android). 🎯 The goal is not to impose censorship, but rather to provide a safe, ethical, and educational alternative. 🤝 I'm looking for: Interested programmers. Note that I'm only 16 years old. The goal is to find someone who will embrace this idea. Suggestions for improving the idea. Any technical or community support is possible.

Over the years, I’ve interviewed around 100 software developers at Google and roughly the same number across my own companies. One thing has become very clear: Resumes don’t work. They’re too noisy. You get flooded with titles, buzzwords, and irrelevant project summaries. So I distilled everything down to one single task. One prompt I can give to anyone — junior or architect — and instantly get a signal. The task? Write a library that calculates the sum of a vector of values. That’s it. No extra requirements. The beauty is that it looks trivial — but the depth reveals itself as the candidate explores edge cases, generalization, scalability, performance, and design. Most junior candidates start like this: int Sum(int* data, size_t num_elements) { int result = 0; for (size_t i = 0; i…  ( 5 min )

Nix is now central to how I structure my workstation setups and manage development and production environments across my projects. Over time, I found myself repeating certain setups. This post is a short note on how I started working with Nix Flake templates to avoid or reduce this repetition. I am actively using Nix from my workstation setup to development environments, from Docker image builds to CI/CD pipelines, and even on production servers. One of the themes that comes up often is provisioning a codebase, a development environment and packaging configuration for a new project. What I usually do is check one of my previous projects and copy the relevant parts of the flake.nix file or default.nix and shell.nix files to the new project. It does not require too much effort.

Objective-C has long been a mainstay in the development of applications for iOS and macOS. Despite the rise of Swift, Objective-C remains a relevant and powerful language, particularly for maintaining legacy code and integrating with newer Swift code bases. As we move into 2025, understanding core patterns like delegation continues to be vital for developers working with Objective-C. Delegation is a design pattern used in Objective-C to pass messages between objects and to provide a mechanism for customization of behavior. It allows one object to delegate tasks to another, enabling a clear separation of responsibilities and enhancing the modularity of applications. Typically, a delegate object implements methods from a protocol to respond to certain events or actions occurring in the deleg…  ( 4 min )

In one of our production data platforms, we used Lambda functions to trigger AWS Glue jobs every time a file landed in an S3 folder. That setup worked fine when there were only two or three data sources. But as the system expanded to support more than 10 folders, it required deploying and maintaining an equal number of nearly identical Lambda functions, each wired to specific prefixes and jobs. The architecture became increasingly brittle and harder to manage. This post outlines how that structure was replaced using EventBridge, with prefix-based filtering and direct Glue job targets. No Lambda. No maintenance overhead. Using S3 events to trigger Lambda comes with several limitations: A single Lambda function can’t be mapped to multiple S3 prefixes Each one requires separate deploymen…  ( 5 min )

To Understand Encapsulation please do check out last post Encapsulation is like a medicine capsule: the outer shell hides the complex ingredient inside, delivering only the intended effect to your body. You don't need to know the chemical makeup to benefit from it. Encapsulation is achieved through the use of access modifiers. Python primarily uses two types of access modifier. Private: Accessible from anywhere. Public: Accessible only within the class. Similarly, in programming, encapsulation wraps data and methods in a class, exposing a simple, controlled interface while keeping the internal details private and secure. Let say I want to make "model" attribute private so that nobody can manipulate the model name. So make it private just add '__model' So, question arise if we can't access attribute but we can access function which include the private attribute. Think of like if we have attribute which you don't want get manipulated then make it private.  ( 3 min )

Introduction If you're developing a MAUI application and are facing issues with the CarouselView control not displaying images from an ObservableCollection, you are not alone. This article will address why images may not show up in your CarouselView, even when the same image sources work perfectly with a standard Image control. Understanding CarouselView in MAUI The CarouselView in .NET MAUI is designed to display a collection of items in a swipeable format. Each item can be customized using a DataTemplate, which lets you define how each item appears. Typically, developers use ObservableCollection to bind dynamic data to CarouselView because it notifies the view of changes. However, while you may see indicators appear correctly, images may not load as expected. Common Issues with CarouselV…  ( 4 min )

Objective-C, a primary programming language used for macOS and iOS development, has always been appreciated for its unique blend of C's efficiency and Smalltalk's dynamism. A critical feature that sets it apart from other languages is its support for **dynamic typing**. This allows for a flexible development process that enhances code modularity and adaptability. But what truly is the purpose of dynamic typing in Objective-C? ## What is Dynamic Typing? Dynamic typing refers to the ability of a programming language to determine the type of an object at runtime, rather than during compile-time. This contrasts with static typing, where the type of an object is known and enforced during compilation. In Objective-C, this means you do not have to specify the class type of an object, providing …  ( 4 min )

If you're still not using Tailwind CSS JIT (Just-in-Time) mode in your development workflow, you're seriously missing out on one of the biggest productivity boosts Tailwind has ever introduced. The JIT compiler doesn't just make your builds faster—it fundamentally changes the way you write utility-first CSS. Once you try it, there’s no going back. Let’s break down why it's a game-changer for modern frontend developers, and how to make the most of it. JIT mode was introduced as a way to: Compile only the CSS classes you actually use Instantly reflect changes as you code Drastically reduce build times and output file size Enable dynamic class generation Instead of scanning your entire project ahead of time, it compiles your CSS on-demand as you save files. That means faster feedbac…  ( 4 min )

Selecting messages with a specified sum of verbosity can be challenging in SQL, especially when the goal is to find all messages where the sum of a specific column stays below a certain threshold. In this case, we want to find messages from a table with a specified verbosity value such that the summed values of verbosity for a given set of rows remain under a specified limit, N. Understanding the Problem In our example, we have a simple table named messages, which contains two columns: id and verbosity. Given the entries: | id | verbosity | |----|-----------| | 1 | 20 | | 2 | 20 | | 3 | 20 | | 4 | 30 | | 5 | 100 | When we wish to choose rows whose sum of verbosity is less than a certain value, say N = 70, we expect to select the rows with ids 1, 2, an…  ( 4 min )

Flutter makes building beautiful UIs fast and fun — but what happens when your app starts growing? When screens need to react to shared data? That’s when state management becomes essential. In this blog, we'll demystify state management in Flutter and help you decide between Bloc, Riverpod, and Provider — three of the most popular approaches in the Flutter ecosystem. State refers to the data your UI depends on. For example: A counter’s value Whether the user is logged in The list of items in a shopping cart State management is how we keep the UI in sync with the data — especially when multiple widgets care about the same data or when data changes over time. There are two broad types: Local state (e.g., setState inside a single widget) Global/shared state (e.g., auth status, theme, user pre…  ( 5 min )

Introduction If you're using Java Development Kit (JDK) 17 and noticing that your call to fieldClass.getDeclaredFields() returns an empty array, you're not alone. Many developers have encountered this issue when attempting to retrieve field information from classes in the Java Reflection API. The Java Reflection API is essential for inspecting classes at runtime, allowing developers to gather information about fields, methods, and constructors programmatically. However, certain security restrictions in JDK 17 can lead to unexpected behavior, including the inability to reflectively access declared fields in classes like Field.class from the java.lang.reflect package. Understanding the Root Cause In JDK 17, Java introduced a more robust module system that enforces strong encapsulation by def…  ( 5 min )

Fine-tuning in Artificial Intelligence (AI) refers to the process of taking a pre-trained model and adapting it to a specific task or dataset. Pre-trained models, especially large ones like GPT (from OpenAI) or BERT (from Google), are initially trained on massive datasets using general-purpose data. These models learn a broad understanding of language, patterns, or image features. However, for specialized tasks—like medical diagnosis, legal document analysis, or customer sentiment detection—fine-tuning helps the model learn domain-specific nuances. The process involves continuing the training of the model with a smaller, task-specific dataset while adjusting the model’s weights slightly. This method allows the model to retain its general knowledge while becoming more effective in the target domain. Fine-tuning is far more efficient than training a model from scratch, saving both computational resources and time. There are different levels of fine-tuning. Some approaches adjust only the final layers of the neural network (known as feature extraction), while others allow all layers to be updated (full fine-tuning). Techniques like parameter-efficient fine-tuning (PEFT), such as LoRA (Low-Rank Adaptation), are gaining popularity, especially for large language models, because they minimize the number of parameters updated. Fine-tuning is used in a variety of real-world applications, including chatbots, image generation, fraud detection, and more. It’s especially powerful in scenarios where labeled data is limited but high-quality outputs are essential. With the growth of open-source and pre-trained foundation models, fine-tuning has become a key skill for AI practitioners. To master techniques like fine-tuning, transfer learning, and prompt engineering, enrolling in a Generative AI certification course is highly recommended.  ( 3 min )

Abstract We introduce a novel numerical method, ExpRoot+Log, for function approximation based on a hybrid linear basis consisting of exponential-square-root, polynomial, and logarithmic components. This method achieves high accuracy across smooth, discontinuous, and rapidly decaying functions while remaining simple, interpretable, and computationally efficient. We show that ExpRoot+Log outperforms classical approaches such as polynomials, splines, Fourier series, and even neural networks in key scenarios, offering a new universal baseline for practical approximation. Introduction Function approximation is fundamental to numerical analysis, physics, machine learning, and signal processing. Classical bases—polynomials, splines, and trigonometric functions—have known limitations, especially near discontinuities or exponential decays. While neural networks provide expressive power, they are complex, opaque, and computationally expensive. We propose a new hybrid basis: This composition handles: All coefficients are learned linearly (e.g., via least-squares), ensuring ultra-fast performance and excellent stability. Numerical Evaluation We tested ExpRoot+Log against standard methods (polynomials, splines, Fourier) across six function types: Sine Exponential decay Step function Gaussian spike Absolute value Composite (piecewise mix) ExpRoot+Log consistently achieved 1–4 orders of magnitude lower error than polynomials or Fourier bases.

Somewhere between thinking and speaking, there’s a strange place where meaning starts to solidify. It’s not quite a word yet. More like a haze of associations. A mental sketch your brain tries to translate into something shareable. Sometimes it works. Most of the time it doesn’t, at least for me. I tend to mumble a lot. That private language in your head, the one you use to talk to yourself, isn’t English or Portuguese or Python. It’s not even a language, really. It’s raw and messy.

Most Job Posts Are Noise Vague requirements Tools thrown in without context Unrealistic experience levels (10 years of Cypress? Sure.) Zero clue what kind of thinking the role actually needs I didn't want that. So I stripped it down and wrote it like I write tests: clear, intentional, and designed to reveal behavior. I ended the post with a line that acted like a trapdoor: “Want in? Send your resume and a short note on how you found your worst bug to hi@proudcloud.io.” That was the test. If you missed it, you failed silently. The Best Testers Didn’t Just Apply. They Investigated. But a smaller group took the time, wrote thoughtful bug stories, and sent real applications to the email provided. And those were the ones I called in for interviews. Some of the best candidates I’ve ever spoken to came from that post. Sound familiar? This Isn’t Just About Hiring The way you write a bug report. The way you name a test. The way you respond when something feels off, even if the build says "green." QA is never just about tools. It's about how you think.

Originally posted at https://qckfx.com/blog/why-engineering-teams-should-build-their-own-ai-coding-agents Imagine walking into an engineering department three years from now. The highest-performing teams will be defined by the proprietary AI systems they've built, customized for their specific codebases, architectural patterns, and business domains. These teams will wield AI as a strategic differentiator, not merely consume it. This is where our industry is clearly headed. As AI increasingly becomes the primary author of code across industries, the strategic advantage will shift from who can write the best code to who can best direct, customize, and optimize AI systems to write that code. The best engineering teams won't achieve these results by simply adopting off-the-shelf AI coding tool…  ( 7 min )

I've worked in several agile teams as both a developer and lead developer. One particular project sticks in my mind — a team of ten people, dozens of microservices, and a lot of GitLab repositories to manage. During each sprint, we were juggling features across multiple repos. At the same time, we were responsible for reviewing each other’s code. Our typical flow was: Open a merge request (MR) on GitLab Move the related Jira ticket Share the MR link in a Teams channel Move on to the next story When the workload was light, it was manageable. But in busy sprints, reviews piled up quickly. Large MRs got ignored, or rushed through. And tracking what was waiting, what was blocked, or what still needed input? A mess. We experimented with several ideas: Using GitLab labels like needs-review or blocked Adding Jira tags Rotating reviewer ownership by repo each sprint They helped — but they didn’t solve the root problem: lack of visibility and timing. Code reviews were often asynchronous and scattered. We were switching contexts constantly, jumping between repos, and forgetting which contributions needed our attention. We didn’t need more tools — we needed a better way to surface and track reviews. Something that would: Give us a unified view of MRs Let us know what’s ready to merge, what’s waiting, and what’s blocked Respect our flow, instead of interrupting it That’s when I started working on a side project, aiming to solve this specific pain point. That side project became Bellugo — a contribution tracker designed to help teams stay on top of reviews across repositories without the chaos. It’s still a work in progress, but if this resonates with your team, I’d love for you to check out the landing page and maybe join the private beta waitlist.  ( 4 min )

So, you're self-hosting awesome apps like Jellyfin, Home Assistant, or your personal blog with Docker. You want that sweet, sweet HTTPS padlock for secure connections, and Let's Encrypt is the obvious choice for free SSL certs. Awesome! You set up your reverse proxy (maybe Traefik, because it's slick!), point it to your app, and tell it to get a certificate... only to hit a wall. Why? Meet the home networker's nemesis: ISPs blocking incoming port 80. The Standard Way (and the Wall) Let's Encrypt's default validation method, HTTP-01, is simple: their servers try to access a special file on your server over standard HTTP (port 80) to prove you control the domain. Let's Encrypt -> Your Public IP:80 -> Does challenge file exist? -> OK! Cert Issued! But if your ISP blocks incoming connections …  ( 5 min )

Learning Redux is a real pain in the @#$#$^&. Good thing the team I was on at the time I learned it highly valued taking the time to learn, because it took me a good 30 out of 40 hours of a work week to figure out what the eff was going on. Once I finally did learn it however, I realized that the majority of what slowed me down in the learning process was that I couldn’t find a great explanation of exactly what Redux was doing. All I could find were tutorials on how to use it, and not really very much info on how it worked. I’m going to try to solve that issue with this post. I’m also going to assume that you know how to use React, and that you know what Redux is and why you want to learn it.

The Testing Time Crisis When our team started building a new fintech application last year, we hit an unexpected bottleneck: testing time. With multiple user roles, complex verification flows, and strict security requirements, our QA cycles grew from days to weeks. This wasn't just frustrating—it was directly impacting our release velocity and team morale. After several painful sprints, we implemented five changes to our testing approach that dramatically reduced our testing time without compromising quality. I'm sharing these because they've been game-changers for us, and they might help your team too. One of our biggest time sinks was manually creating test users with different permission levels. We solved this with an automated provisioning system. // Example of our user provisioning …  ( 5 min )

If you've ever found yourself creating multiple Gmail accounts just to test a simple registration flow, you know the pain I'm talking about.

🎯 Learning Goals What are the characteristics of Singly Linked Lists? What are its time complexities? ListNode? Has a value and a next pointer next is a reference to another ListNode Order in memory may not be contiguous (unlike arrays which are) Simple while loop with a current pointer can be used: cur = ListNode1 while cur: cur = cur.next ⌚ Time complexity is O(n) , where n is the number of nodes in the linked list Now if the Linked List is circular (i.e. last node points back to first) traversing like this would cause an infinite loop. It would be helpful if we’re keeping track of the head and the tail of the linked list using pointers Advantage over array is that inserting is always O(1) even if we insert in middle. Let’s say we wanna add at the end or tail : tail.next = NewListNode tail = NewListNode # or this line 'tail = tail.next', both are correct ⌚ Time complexity is O(1) Removing any node is constant time ASSUMING we have a pointer to the previous node. Let’s say we wanna remove the second node: head.next = head.next.next # Just set the next pointer of head to the one after the deleted node Can be assumed that garbage collection will take place for the deleted node ⌚ Time complexity is O(1) For both of these operations, the caveat is if we don’t have a reference to the node at the desired position (head or tail), the time will still be O(n) Operation Big-O Reading/ Access O(n) Traversal/ Search O(n) Insertion O(1)* Deletion O(1)* *Assumes you have a reference to the node at the position (if not it is O(n) ) 206.

Key Takeaways: The Fed may pause rates but inject liquidity. Crypto could rally as a recession hedge. The weak US dollar and gold rally signal a shift to scarce assets. The US Federal Reserve Open Market Committee (FOMC) interest rate decision on May 7 will be a defining moment for risk-on assets, including cryptocurrencies. While the consensus points to no change in interest rates, Bitcoin (BTC) and altcoins could see gains if the US Treasury is compelled to inject liquidity to stave off an economic recession. A more accommodative monetary policy could stimulate activity, but the Federal Reserve (Fed) is also contending with a weakening US dollar. Some analysts argue that a US interest rate cut may fail to stimulate growth as recession risks persist, potentially creating an ideal envir…

Key Takeaways: The Bitcoin Risk-Off signal dropped to 23.7, its lowest since March 2019, indicating low correction risk and a high likelihood of a bullish trend developing. Despite the recent decline in network activity, bullish macro indicators like the Macro Chain Index (MCI) suggest Bitcoin could soon rally above $100,000. On May 5, the Bitcoin Risk-Off signal, an indicator that uses onchain and exchange data to assess correction risk, dropped to its lowest level (23.7) for the first time since March 27, 2019, when Bitcoin (BTC) traded at $4,000. The signal is currently in the blue zone, which historically suggests low correction risk and a high probability of a bullish trend. When the oscillator rises above 60 or turns red, it implies a high risk of bearish movement.  Bitcoin Risk-O…

Opinion by: Barna Kiss, CEO of Malda An idea recently floated by some prominent thinkers in the Ethereum space to reclaim value for the mainnet is the taxing of its Layer-2s. The future of Ethereum does not depend on policy but on enabling frictionless capital movement between the L2s in question. Tariffing rollups may appear a neat way to reclaim value for the mainnet. In practice, it would fragment the ecosystem, drain liquidity, push users toward centralized platforms, and avoid decentralized finance altogether. In a permissionless system, capital flows to where it is treated best, and Ethereum's rollups mistreat it. Liquidity fragmentation is Ethereum's real threat In traditional finance, the link between fluidity and growth is well established. Lower barriers to capital inflows lead …

Why finance veterans are still skeptical about blockchain Blockchain has been part of the finance conversation for over a decade now.

This question reflects a few key ongoing skepticisms about blockchain within finance.

But actually applying those promises across banking, accounting and operations is still complicated. A 2021 APQC survey identified the main hurdles: a lack of industry-w…

Representative Maxine Waters, ranking member of the House Financial Services Committee (HFSC), led Democratic lawmakers out of a joint hearing on digital assets in response to what she called “the corruption of the President of the United States” concerning cryptocurrencies. In a May 6 joint hearing of the HFSC and House Committee on Agriculture, Rep. Waters remained standing while addressing Republican leadership, saying she intended to block proceedings due to Donald Trump’s corruption, “ownership of crypto,” and oversight of government agencies. Digital asset subcommittee chair Bryan Steil, seemingly taking advantage of a loophole in committee rules, said Republican lawmakers would continue with the event as a “roundtable” rather than a hearing. HFSC Chair French Hill urged lawmakers at the hearing to create a “lasting framework” on digital assets, but did not directly address any of Rep. Waters’ and Democrats’ concerns about Trump’s involvement with the crypto industry. He claimed Waters was making the hearing a partisan issue and shutting down discussion on a digital asset regulatory framework. This is a developing story, and further information will be added as it becomes available.

Democratic lawmakers in Washington are backing off support for crypto legislation amid heightened concerns over corruption, including the conduct of the Trump family’s World Liberty Financial (WLFI). In March, the GENIUS Act, which would regulate stablecoins in the US, passed a critical committee reading with the support of several pro-crypto Democrats. Democratic Senators Ruben Gallego, Mark Warner, Lisa Blunt Rochester, Andy Kim and Angela Alsobrooks voted with Republicans, opposite lead Democrat and prominent crypto critic Senator Elizabeth Warren. The bill passed the committee only after a number of changes were made, including stricter requirements for stablecoin issuers and provisions for Anti-Money Laundering, countering terrorism financing and risk management procedures.  Now, it s…

Key takeaways: Bitcoin’s Coinbase premium index turned negative for the first time in 15 days, indicating defensive short-term sentiment among US investors. Bitcoin CME futures gaps between support at $92,000-$92,500 and resistance at $96,400-$97,400 suggest a period of range-bound trading. Bitcoin’s Coinbase premium index, which measures the gap between BTC price at Coinbase Pro and Binance exchange, turned negative after a 15-day positive stint, signaling potential bearish sentiment among US investors. This drop coincides with Bitcoin (BTC) slipping below $94,000, and the premium’s decline suggests reduced buying pressure on Coinbase, which is viewed as a proxy for both institutional and retail demand.

While blockchain infrastructure may be ready for institutional use, many legal teams at large firms remain cautious about full integration with the technology.  At the Token2049 event in Dubai, DoubleZero Labs founder and former Solana head of strategy Austin Federa told Cointelegraph that today's high-performance blockchains like Solana are technically capable of supporting large-scale institutional usage. However, lawyers still need to catch up.  “Most blockchains nowadays, especially things like Solana, are fast enough for institutions to use them,” Federa said. “It’s really more about the institutions and the institution’s lawyers getting comfortable with crypto.” Federa added that institutional lawyers and compliance teams are still addressing regulatory concerns. The executive said t…

Decentralized autonomous organization (DAO) HydraDAO claims that its researchers were able to use a novel technique to repair severed spines in rats. In a May 5 X post, decentralized science (DeSci) project HydraDAO said that one of its research projects resulted in “rats who had their spines fully transected” being able to walk again. More notably, recovery from surgery reportedly only took five days. Source: HydraDAO The post featured a video of partially shaved (presumably due to surgery) rats walking in what appeared to be a laboratory setting.

The dedicated HydraDAO page reads: “The Dowell team submitted a project proposal to HydraDAO. After ca…

Petr Kozyakov, CEO of crypto payments platform Mercuryo, told Cointelegraph that the future of finance may not be a winner-takes-all scenario but a blend of digital assets and fiat, each used where it makes the most sense.  In a Cointelegraph interview, Kozyakov said that while crypto payments are seeing an increase in adoption and demand, the asset class won’t be fully replacing fiat money anytime soon. He said the two asset classes will coexist, with people choosing the more convenient payment option in different situations.  “We don’t think crypto will replace fiat,” Kozyakov told Cointelegraph. “They will coexist, and people will turn to crypto when it’s the easier, more practical option, whether that’s for payroll, yield or money transfers.” Mercuryo Petr Kozyakov at the Token2049 eve…

Crypto exchange OKX’s CEO for its Middle East and North Africa (MENA) arm urged the industry to focus on delivering real-world utility as interest in real-world asset (RWA) tokenization accelerates.  In a Cointelegraph interview at the Token20249 event in Dubai, OKX MENA CEO Rifad Mahasneh warned that while tokenization is promising, projects must “clearly demonstrate” the benefits of tokenizing specific assets.  “In some cases, we’re tokenizing things that don’t need tokenization, but in some cases, we’re tokenizing things that actually give you real, everyday value, right? And if you can see that everyday value, then that is a promising project,” Mahasneh told Cointelegraph. He said hype can drive project growth in the Web3 space, but providing everyday value should be the priority.  OKX…

Opinion by: Simon Cain, contributor at Bitcoin Policy UK Most jurisdictions globally are researching, developing or implementing retail central bank digital currencies (CBDCs). If you see these as harmless move-with-the-times digital updates of old-fashioned paper money, look again. CBDCs potentially mean financial serfdom via a monetary panopticon where the authorities closely control every transaction.  If you think this sounds paranoid, just consider the words of Augustin Carstens, head of the Bank for International Settlements — the central bank for the world’s central banks. Lamenting the authorities’ current inability to control cash transactions, he says that with a CBDC, a “central bank will have absolute control on the rules and regulations that will determine use... also we will …

Efforts to pass crypto legislation in the US Senate face mounting resistance amid growing ethical concerns around US President Donald Trump’s ties to crypto. In a May 5 letter to the US Office of Government Ethics, Senators Elizabeth Warren and Jeff Merkley said that Trump and his family stand to personally profit from an investment involving UAE state-backed firm MGX, crypto exchange Binance and World Liberty Financial (WLFI). The senators called for an urgent probe, warning the deal may violate the US Constitution’s Emoluments Clause and federal bribery statutes. At the center of the controversy is WLFI’s USD1 stablecoin, reportedly chosen for a $2 billion investment MGX plans to make into Binance. The senators said the transaction amounts to a potential backdoor for foreign influence an…

Bitcoin Core developers have decided to remove a limit on transaction data in the next network upgrade, enabling more data to be included in a more efficient way.  “Bitcoin Core’s next release will, by default, relay and mine transactions whose OP_RETURN outputs exceed 80 bytes and allow any number of these outputs,” read the announcement on GitHub by Bitcoin developer Greg Sanders on May 5.  The long-standing limit was originally a “gentle signal that block space should be used sparingly for non-payment proof of publication data,” has outlived its utility, he added.  The proposal (PR 32359) was created by Bitcoin pioneer Peter Todd at the request of Chaincode Labs.  OP_RETURN is a special type of Bitcoin (BTC) transaction output that allows storing small amounts of data on the blockchain,…

Alex Mashinsky, the founder and former CEO of bankrupt crypto lending platform Celsius, has blasted the government's 20-year “venom-laced” sentence request, declaring it a “death-in-prison sentence.” The US Department of Justice requested Mashinsky receive at least 20 years behind bars in the May 8 sentencing for his role in misleading Celsius users and profiting from the price manipulation of Celsius (CEL), which would make the 59-year-old 79 if he serves the whole sentence. Lawyers acting for Mashinsky argued in a May 5 reply memorandum filed in a New York district court that he should receive no more than 366 days, because the DOJ hasn't taken into account his status as a nonviolent first-time offender with a previously unblemished 30-year history in business.   “The government's venom-…

Two Florida crypto bills have been removed from the legislative process in the latest blow to American state-level strategic Bitcoin reserve ambitions.  Florida’s House Bill 487 and Senate Bill 550 have been “indefinitely postponed and withdrawn from consideration” on May 3, according to the Florida Senate.  Florida’s legislative session adjourned on May 2 without the passage of these two bills, which would have advanced legislation to establish a crypto reserve for the state. The Senate and House agreed to extend the session until June 6 to address budget plans.  Lawmakers passed about 230 bills during the session, dealing with things like prohibiting putting fluoride in the water, protecting state parks, and a school smartphone ban, but diversifying state treasury portfolios was not amon…

The Tron network has drawn closer to regaining the lead from Ethereum in Tether circulation after another big mint by the US stablecoin issuer. On May 5, Tether minted another $1 billion Tether (USDT) on the Tron network, according to Arkham Intelligence. This brings the total USDT on Tron to $71.4 billion, according to the Tether Transparency report.  In comparison, there is currently $72.8 billion USDT circulating on the Ethereum network, so just $1.4 billion more USDT on Tron will see it become the leading network for the world’s largest stablecoin issuer, as it has been previously over the last two years.  Tron was ahead of Ethereum for USDT circulation between July 2022 and November 2024, but a large $18 billion mint on Ethereum pushed the network ahead again, according to CryptoQuant…

The new “Digital Asset Market Structure Discussion Draft” introduced by House Republicans on May 5 could work to reduce the dominance of large crypto firms and promote more participation in the broader market, according to an executive from Paradigm.  The discussion draft, led by the House agricultural and financial services committee chairs Glenn Thompson and French Hill, is an “incremental, albeit meaningful, rewrite” of the Financial Innovation and Technology for the 21st Century Act (FIT21), Paradigm’s vice president of regulatory affairs Justin Slaughter said in a May 5 X post.

Samourai Wallet’s lawyers allege federal prosecutors suppressed advice that the firm didn’t need a license before they charged executives at the crypto mixing service months later.  In a May 5 letter to a Manhattan federal court, lawyers for Samourai co-founders Keonne Rodriguez and William Hill said prosecutors disclosed that the US Treasury Department’s Financial Crimes Enforcement Network (FinCEN) representatives told them six months before they charged the pair “that under FinCEN’s guidance, the Samourai Wallet app would not qualify as a ‘Money Services Business’ requiring a FinCEN license.” “Shockingly, six months later, the same prosecutors criminally charged Keonne Rodriguez and William Hill with operating just such a business without a FinCEN license,” the lawyers added.

Introduction When compiling programs in C or C++ using cc or c++, you may find yourself needing to use a different linker than the default one. For instance, your version of GCC or Clang might link against /usr/bin/ld. In many scenarios, developers want to test their applications with alternative linkers, like /usr/local/bin/ld, for various reasons, including performance evaluation or compatibility testing. In this article, we’ll explore how to specify a different linker without running separate compilation steps. Why the Default Linker Matters The linker plays a crucial role in the compilation process, as it's responsible for combining different object files into a single executable.

“The computer industry is the only industry that is more fashion-driven than women’s fashion.” Larry Ellison In our era, the cloud is the haute couture of infrastructure. Everyone wants it. Everyone says you need it. And few ask whether it actually fits. This post is for those who remember that not every problem needs 12 layers of abstraction. It's for careful builders who believe that owning your tools is better than renting your soul. And here are 12 reasons why on-premise will outlast the hype. The cloud sells convenience, but charges premium rent, forever. When you buy servers, you own an asset. When you rent a VM, you feed a meter. The cloud is like living in a hotel room and bragging you don’t have to fix the faucet. Sure, but you’re paying 10× the mortgage and still can’t open a w…  ( 7 min )

Understanding the Issue with Modal Animations If you've ever tried to implement a modal that slides in from the bottom after being triggered by a button, you might have encountered an unexpected behavior when using a element inside your modal dialog. This is a common issue that developers face, especially when working with CSS animations. In this article, we will explore why this issue occurs and how you can fix it effectively. Why Does This Happen? The problem often arises from the way CSS handles layout changes during animations. When the modal is opened, if a button element is included, it may trigger a reflow in the browser’s layout engine. This reflow can result in the appearance of a scrollbar, which disrupts the fluidity of your animation. The pointer-events property combin…  ( 4 min )

Você já digitou algo em um campo de busca e, a cada letra digitada, uma nova requisição era feita para a API? Isso é ineficiente. A solução? debounce() debounce? É uma técnica usada para adiar a execução de uma função até que um tempo específico tenha passado sem novas chamadas. É muito usado em: buscas dinâmicas (auto-complete) eventos de rolagem (scroll) eventos de resize Imagine um campo de busca que chama a API a cada tecla: function search(term) { fetch(`https://api.exemplo.com/search?q=${term}`) .then(res => res.json()) .then(console.log); } input.addEventListener("input", (e) => { search(e.target.value); }); Isso gera chamadas demais. Agora, com debounce: function debounce(fn, delay) { let timer; return (...args) => { clearTimeout(timer); timer = setTimeout(() => fn(...args), delay); }; } const debouncedSearch = debounce(search, 500); input.addEventListener("input", (e) => { debouncedSearch(e.target.value); }); Agora só é chamada a API depois que o usuário parar de digitar por 500ms. No React, pode usar com useCallback ou bibliotecas como lodash.debounce: import debounce from 'lodash.debounce'; const debounced = useCallback( debounce((value) => { // chamada de API aqui }, 300), [] ); Conta aqui nos comentários como implementou 👇 Ou salva esse post pra usar depois! 🔖  ( 3 min )

Introduction If you're working with Hibernate and querying a DB2 z/OS database, you might have faced a common issue where the generated SQL queries include unnecessary cast statements, especially after upgrading to Hibernate 6. This can cause errors as certain DB2 versions don't support those casts. In this article, we will explore why this issue occurs and provide solutions to remove the cast statements for compatibility with DB2 z/OS. Understanding the Problem In Hibernate, SQL query generation can change between versions due to changes in how Hibernate handles type conversions.

When working with deeply nested arrays in Laravel, especially when handling configuration files, API responses, or multidimensional data structures, managing or accessing values quickly becomes complex. Laravel’s Arr::dot() method offers a clean, efficient way to flatten these arrays using “dot” notation, making them much easier to work with. In this article, we’ll explore what Arr::dot() does, how it works, and when you might want to use it. The Arr::dot() method in Laravel flattens a multidimensional array into a single-level array using dot notation for keys. This transformation allows you to access deeply nested values with a simple key string. Arr::dot(array $array, string $prepend = '') $prepend: (Optional) A string to prefix each key in the final array. This method is part of Laravel’s Illuminate\Support\Arr helper class. Let’s take a look at a typical example: Input Array $data = [ Applying Arr::dot() $flattened = Arr::dot($data); print_r($flattened); [ 'user.name' => 'John', 1. Configuration Files 2. Localization 3. Form Handling Bonus: Reversing the Flattening $nested = Arr::undot($flattened); Arr::dot() is a small but powerful utility in Laravel that simplifies the handling of complex arrays. Whether you're building APIs, working with config files, or cleaning up nested data structures, this helper can be a time-saver and make your code cleaner and more readable. Next time you're faced with a deeply nested array, consider reaching for Arr::dot() — you’ll appreciate the simplicity it brings.  ( 4 min )

Comprehensive Exploration of the Permissions API for Managing User Consent Historical and Technical Context The emergence of web technologies has ushered in a new era of interactivity and real-time applications. However, with such capabilities comes the critical responsibility of user privacy and consent. The Permissions API was standardized as part of the broader movement to provide enhanced privacy practices on the web, enabling developers to manage user permissions more systematically. The Permissions API was introduced to address the concerns posed by previous blind consent models, which often left users unaware of the degree of access they were granting. Traditionally, permissions like location access, notifications, and camera/microphone use were either all-or-nothing, l…  ( 6 min )

Creating a multi-page registration form in PHP can be cumbersome, especially when the pages require reloading for navigation. If you're experiencing slow load times with your current method—where each page requires a new HTTP request—you might want to consider converting your form into a Single Page Application (SPA). This approach enhances user experience by loading the HTML just once and using JavaScript to handle navigation smoothly. Understanding the Issue When using multiple pages for form registration, each time a user clicks the 'Next' button, a new HTTP request is sent to the server, which loads a new page. This results in a complete refresh, including reloading CSS, JavaScript, and images, leading to inefficient use of resources and slow loading speeds. A Single Page Application a…  ( 4 min )

I like testing new browsers, these days I use Firefox more than chrome, but I always have Opera and Edge. Today I saw this video https://youtu.be/9YM7pDMLvr4?si=R7X_wdJVqqRB3TNB Andreas explaining what is Ladybird browser and why they are developing it. So I went to https://github.com/LadybirdBrowser/ladybird checked out the code and build it on WSL2 Windows 11, took around 3 hours to compile and finally it worked UI looks similar to Firefox and feels like #Netscape in 1999, and it is developed actively, I hope we have a new and free browser because feels like Firefox is not that free anymore and Google has been too strong on browser market, it would be nice to have a real non-profit browser here. Maybe government/countries should support this kind of organizations otherwise browsers or OSes becoming like citizen monitoring tools and used for profit and manipulation, After we say internet is a human right that human should have the option of non monitored communication use in their home. And in the YouTube video Andreas talks about SerenityOS which looks very similar to Windows 95, good old days. It is a good idea to have unix like OS as desktop.

Em janeiro, decidi tirar minha ideia de SaaS do papel. O objetivo? Aprender na prática como levar um produto do conceito à loja. Confesso que foi uma onda de desafios (e ainda está sendo!). Como era meu primeiro projeto, cometi vários equívocos. Eu queria compartilhar alguns abaixo ⤵️ — e como eles estão me ajudando a evoluir: 🔥 Planejamento impulsivo   Fui direto da ideia para a solução, sem mapear etapas ou prazos. Resultado? Retrabalho e ansiedade. Hoje, priorizo ferramentas de gerenciamento e cronogramas flexíveis para manter o foco sem engessar a criatividade. 🔍 Validação superficial   Criei o SaaS para resolver meu problema, mas não validei se era uma dor real do mercado. Consequência? Perdi tempo competindo com soluções já consolidadas. Aprendi que entrevistas com potenciais usuários são tão importantes quanto o código. 💸 Precificação "no feeling"   Foquei em funcionalidades incríveis, mas não pensei em como monetizá-las de forma atraente. Lição? Agora estudo modelos de precificação antes de sair desenvolvendo novas features, usando cases de sucesso como referência. ✨ O saldo positivo?   Esses tropeços me deram algo valioso: clareza. Hoje entendo melhor que errar faz parte do processo — desde que cada erro vire um degrau para iterar. E você? Já passou por situações assim em seus projetos?  ( 3 min )

In 2025, DevOps is not just about shipping code faster. It's about delivering resilient, scalable, and secure systems while maintaining harmony across development and operations. Here’s a look at the most relevant KPIs DevOps teams should track in 2025 to ensure performance, productivity, and reliability are all on target. Deployment Frequency Why it matters: This KPI measures how often you deploy code to production. High-performing DevOps teams typically deploy multiple times per day. How to improve: •Automate CI/CD pipelines •Embrace feature flags and trunk-based development •Encourage smaller, incremental releases Pro tip: Pair this metric with Change Failure Rate to ensure quality isn't sacrificed for speed. Lead Time for Changes Change Failure Rate (CFR) Mean Time to Recovery (MTTR) System Uptime & Availability Developer Productivity Infrastructure as Code (IaC) Coverage Security Scan Success Rate Final Thoughts Want to dive deeper?

Hey dev.to! GAEB4Linux, which aims to bring native support for GAEB files (a German construction industry standard) to Linux. GAEB is a widely used XML-based format for exchanging construction data in Germany. It’s essential for things like bills of quantities, tender submissions, costing, and invoicing. There are plenty of GAEB software tools available, but almost all of them are Windows-only or commercial. Linux users in the construction industry currently have no solid open-source solution to handle GAEB files. The goal is to create an open-source GAEB file viewer/editor for Linux (written in Java for cross-platform compatibility). The initial version will support: Viewing GAEB XML files (e.g., .X83, .X84), Entering bid data and prices for tenders, Later stages could include additional features like full AVA (tendering and invoicing) functionality. 🌱 Current Status: Right now, I’m in the early planning phase – no code has been written yet. I’m designing the system, figuring out the core features, and planning how to integrate the GAEB XML structure. Developers familiar with Java, XML, and GUI design (Swing/JavaFX, etc.), Anyone with experience in the construction industry or knowledge of GAEB/AVA workflows, Designers or UX/UI specialists who can help build an intuitive interface, Feedback from anyone who has worked with GAEB or similar standards. I’m planning to host the project on GitLab, and I’ll set up a chat (Discord/Matrix) for discussions and collaboration. Would love to hear your thoughts or suggestions, and I’m open to any tips from anyone who has experience with GAEB file handling. Thanks for reading! —Klaus  ( 3 min )

If you've spent time working with JavaScript's asynchronous model, you know that its single-threaded nature is both a blessing and a curse. On one hand, you don't have to worry about complex locking mechanisms. On the other, you might stumble into weird issues where your code just... never runs. One such issue is starvation. In the context of JavaScript, starvation refers to a situation where a task is perpetually delayed because the event loop is constantly busy with other tasks—usually of higher priority or those scheduled more frequently. Since JavaScript executes code in a single-threaded environment using an event loop, starvation can occur when: Long-running synchronous code blocks the event loop. Microtasks (Promises, MutationObservers, etc.) continuously prevent macrotasks (like se…  ( 4 min )

TL;DR: LLMs are great, but they’re not your safety net. Please, for the love of all things holy, test your code. We’re in the golden age of vibe coding. LLMs scaffold our code, fix our syntax, and fill in the blanks. We’re thinking more about architecture and less about syntax—and that’s great. But in all this abstraction, we sometimes skip something essential: testing. AI doesn’t run your code. It doesn't know if that method exists, if that call will throw an error, or if that edge case breaks everything. It’s bluffing with confidence. You can’t vibe your way through correctness. You need tests to know your code behaves the way you think it does. 🛡 Confidence to refactor without fear 🧠 Clarity around what your code is supposed to do 🔄 Continuity when you revisit the code 6 months later 🤝 Collaboration with teammates who now understand the logic A mentor once told me: “Start at the center—your happy case. Then go left, right, and fall off the line.” Say your function expects a positive integer. Start with 42. Then try: 0, -1, Infinity, -Infinity A string ("hello"), a float (3.14), or null Now take it further: What if the parameters are undefined? What if the database call fails? What if the API returns malformed or missing data? What if a field you depend on is null? The real world is messy. Your tests should be ready for that. As we stop writing every line ourselves, we need to start questioning every line more. AI will get you to “working”—but testing gets you to “works when it matters.” AI bluffs. Don’t let it bluff you into a broken release.  ( 3 min )

Grumphp es un orquestador que permite configurar el uso de herramientas de código estático para PHP. Hasta hace relativamente poco tiempo he usado W4D como entorno de desarrollo en mis proyectos, pero hace un año me tocó probar Ddev para un proyecto y desde entonces me enamoré de todo lo que aporta este software. Ahora toca migrar proyectos que tengo con W4D a Ddev y una de las cosas que toca migrar es Grumphp. Para instalar Grumphp yo uso el paquete de Carcheky que está preparado para funcionar con Drupal y luego lo personalizo. Ejecuto el siguiente código para instalar el paquete: composer config extra.grumphp --json '{"config-default-path": "vendor/carcheky/drupal-grumphp/configs/grumphp.yml"}' ; composer require --dev carcheky/drupal-grumphp -W Una vez instalado copio el archivo grumphp.yml que se encuentra en vendor/carcheky/drupal-grumphp/configs/grumphp.yml a la misma altura del archivo composer.json En el archvio composer.json busco la configuración de grumphp y actualizo config-default-path de la siguiente manera: "grumphp": { "config-default-path": "grumphp.yml" } En el archivo grumphp.yml que hemos copiado a la raíz del proyecto buscamos la configuraciónde git_hook_variable y lo actualizamos de la siguiente manera: git_hook_variables: EXEC_GRUMPHP_COMMAND: ddev exec php Por último en la consola ejecuto el siguiente comando para actualizar la configuración del hook pre-commit ddev exec grumphp git:init De esta forma actualizaremos el hook pre-commit de nuestro proyecto (los hooks pre-commit están en la ruta '/.git/hooks/pre-commit`y el archivo queda así: `bash DIFF=$(git -c diff.mnemonicprefix=false -c diff.noprefix=false --no-pager diff -r -p -m -M --full-index --no-color --staged | cat) export GRUMPHP_GIT_WORKING_DIR="$(git rev-parse --show-toplevel)" (cd "./" && printf "%s\n" "${DIFF}" | ddev exec php 'vendor/bin/grumphp' 'git:pre-commit' '--skip-success-output') `  ( 3 min )

📘 Why This Blog? When I first encountered the Builder Design Pattern, it felt over-engineered—like too many classes just to build an object! clicked. This devblog is my honest take on helping you understand the Builder Pattern—the way I wish someone had explained it to me. The Builder Pattern helps construct complex objects step by step. In simple terms: You control the construction process, one method at a time. You might be looking at a Builder Pattern if you see: A class with many constructor parameters (some optional).

Written by David Omotayo✏️ The React compiler is one of the biggest updates to the React framework in years. Last year, the React team released a beta version. Around that time, I wrote an article called “Exploring React's Compiler: A Detailed Introduction”. It unpacked the core idea behind the compiler and showed how it could improve React development by automatically handling performance issues behind the scenes. When the beta dropped, the React team encouraged developers to try it out, give feedback, and contribute. And many did. A standout example is Sanity Studio. They used the compiler internally and shipped libraries like react-rx and @sanity/ui that are optimized for it. Thanks to contributions like these, the React team officially released the first Release Candidate (RC) on Apr…  ( 10 min )

Ever felt like you're drowning in data? You're not alone. In today's digital world, applications generate and consume information at an unprecedented rate. Choosing how and where to store that data in the cloud is one of the most fundamental – and often confusing – decisions architects and developers face. Pick the wrong type, and you could end up with slow performance, skyrocketing costs, or an architecture that just doesn't scale. You look at the AWS console, and the options seem endless: S3, EBS, EFS, FSx... what's the difference, and when should you use each?

Introduction If you're new to Angular and transitioning from server-side development, one common challenge is configuring your application to dynamically connect to your Spring REST API. While hardcoding URLs might be the simplest immediate solution, it often causes issues when deploying to different environments. In this article, we will discuss various approaches to effectively manage API URLs in your Angular application, ensuring a smooth deployment process. Understanding API URL Management When building applications that interconnect with REST APIs, it's crucial to manage API URLs efficiently. Typically, during development, you'd use one server endpoint (localhost), while production might require a completely different URL. Hardcoding API endpoints makes it challenging to adapt to thes…  ( 5 min )

Closures in Go are powerful but come with hidden memory implications.

It all started back in 3rd sem — during one of my computer lab session. My friend had just executed his code — and it worked perfectly. So what happened? He had to log into Gmail on the lab PC That’s when I had this thought: Googled and found already existing ones like dontpad So, for the next couple of weeks, all of us started using dontpad — mostly just copy-pasting code, sharing it as soon as someone got it working. Whoever cracked the problem first would dump the code there, and the rest of us would just grab it and run. Then one day, I was sitting in class and noticed how our teacher logged into her Gmail just to download a PPT and present it to the class.

Incidents in cloud and SaaS tools block users just as hard as faults in your own code. The fix comes faster when the same on-call queue covers both. IsDown now plugs straight into Better Stack through a native API connection. Every outage that IsDown detects shows up as an incident in Better Stack, follows your existing escalation rules, and clears automatically once the vendor recovers. Vendor downtime seldom triggers your own uptime probes—the traffic never reaches you. IsDown closes that gap by checking hundreds of official status pages round the clock. When those signals land inside Better Stack, responders work from a single incident list. No tab-hopping, no split workflows. A shared queue also tightens communication. Stakeholders follow one channel, post-mortems cover both internal a…  ( 4 min )

** ** What is data? Data, in its simplest form, is raw, unprocessed facts and figures. It can be numbers, text, images, or any other form of information that can be stored and processed by computers. Data becomes meaningful information when it is analyzed, interpreted, and placed in context. Therefore, Data is the basic unit of information before it's been organized, analyzed, or interpreted. What is information? In data science, splitting your dataset effectively is an important initial step towards building a robust model. Generally, you'll want to allocate a larger portion of your data for training, very often around 70%-80%, with the remaining 20%-30% for testing. This allows the model to learn from a substantial amount of data while still retaining enough unique data points to test …  ( 8 min )

TS1436: Decorators must precede the name and all keywords of property declarations TypeScript is a robust, statically-typed programming language designed as a superset of JavaScript. Simply put, it enhances JavaScript by adding type definitions (a way to explicitly define the type of values) and other powerful features like interfaces, enums, and decorators. This makes it easier to work with larger codebases and prevent runtime errors by catching issues during the compile time. For those just starting out, think of TypeScript as a tool that adds structure and safety to JavaScript without changing its core nature. If you're building complex applications or working in a collaborative team, TypeScript helps make your code predictable, maintainable, and scalable. Type definitions form the c…  ( 6 min )

If your organization relies on software to deliver value, APIs are already at the epicenter of your digital infrastructure. They connect your systems, enabling you to scale through integration and automation and deliver superior customer experiences. But what’s often overlooked is that APIs are only as reliable as your ability to test them effectively. Unlike traditional UI testing, which focuses on the frontend layer, testing them gives you visibility into the actual mechanics of your app—the business logic, the rules that drive decisions, and the integrations that connect your systems. If you don’t validate that layer thoroughly, you leave core functionality exposed, increasing security risk.

When I first got into software development, we used to deploy our code on EC2 instances and have a minimal continuous delivery setup realized via webhooks that triggered the git pull command and restart nginx, but we also had a bunch of recurring tasks That had to be invoked at midnight (classic example). Some of them had to run every couple of minutes. I remember learning the cron syntax at that time, it felt almost like RegExp, but surely, it was 1000 times easier, however, this is not what I want to talk about. Over time, a lot of tools that I used for softwar…  ( 7 min )

I recently completed the "Develop GenAI Apps with Gemini and Streamlit" course as part of the Google GenAI Exchange Program. This course focused on building interactive, user-friendly GenAI applications by combining Gemini, a powerful language model, with Streamlit, a framework for quickly developing web apps. Through hands-on practice, I learned how to integrate Gemini’s natural language understanding capabilities into Streamlit apps, enabling them to generate dynamic and relevant responses. Streamlit made the process of building these applications faster and more intuitive by offering simple tools to create interactive user interfaces. By the end of the course, I gained the skills to deploy AI-powered apps that can handle user input, process data, and generate real-time results—all with minimal code. This has opened up new possibilities for creating intelligent, real-world applications that leverage the power of Gemini and Streamlit.  ( 3 min )

Originally published at ssojet Slack's Developer Experience (DevXP) team recently implemented significant optimizations to their end-to-end (E2E) testing pipeline, achieving a 60% reduction in frontend build frequency and a 50% decrease in overall build time. These enhancements streamline the continuous integration and deployment (CI/CD) process, allowing engineers to iterate rapidly and efficiently. Slack's existing repository utilizes a CI/CD pipeline that runs E2E tests prior to merging code into the main branch. This process validates changes across the entire application stack, including frontend, backend, and database. However, the team found that frontend builds occurred even when no frontend-related changes were made, leading to unnecessary long build times and resource consumptio…  ( 5 min )

AI agents are becoming an essential part of modern software systems. They can take user input, reason through goals, and interact with external services to complete real tasks. This makes them useful for building workflows, automation, and product features powered by language models. To support this, OpenAI introduced the Agents SDK on March 11, 2025. The SDK provides a way to define agent behavior, connect to external tools, and manage the flow of actions. They ahve also extended the support for MCP recently. Tools are exposed through MCP (Model Context Protocol), a standard interface that lets agents discover and call functions from any compatible server. Today, we will use the OpenAI Agents SDK to build a working Composio MCP agent. The goal is to show how agents can be connected to re…  ( 10 min )

Introduction Upgrading an application to .NET Core 3 often brings a variety of enhancements, one of which is the option to publish a single-file executable. While this has its advantages, many developers encounter path-related issues during the build process, particularly related to the PublishSingleFile flag. This article addresses a common problem where the executable path defaults to a temporary directory, disrupting access to vital resources. Understanding the Issue When you set the PublishSingleFile flag, the .NET runtime modifies how executable paths are resolved. Instead of locating the executable file in its original directory, it often redirects to a location like /var/tmp/.net/. This behavior occurs due to the way the runtime handles unpacking the single-file executable at runtim…  ( 5 min )

Arrays are fundamental data structures in Java that store multiple values of the same type in a single variable.

Exceptions in Java are events that disrupt the normal flow of a program's execution. They are used to handle errors and other exceptional events that may occur during runtime. Checked Exceptions (compile-time exceptions) Must be declared or handled (using try-catch or throws) Examples: IOException, SQLException, ClassNotFoundException Unchecked Exceptions (runtime exceptions) Not checked at compile time Examples: NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException Errors Serious problems that applications should not try to catch Examples: OutOfMemoryError, StackOverflowError Exception Handling Keywords try: Block of code to monitor for exceptions catch: Block that handles the exception finally: Block that always executes (for cleanup) throw: Used to explicitly throw an exception throws: Declares exceptions that might be thrown by a method try { // Code that might throw an exception int result = 10 / 0; // This will throw ArithmeticException } catch (ArithmeticException e) { System.out.println("Cannot divide by zero!"); } catch (Exception e) { System.out.println("General exception caught"); } finally { System.out.println("This will always execute"); } You can create your own exception classes by extending Exception (checked) or RuntimeException (unchecked): class MyCustomException extends Exception { public MyCustomException(String message) { super(message); } } Catch specific exceptions rather than general Exception Don't ignore caught exceptions (empty catch blocks) Use finally blocks for resource cleanup Document exceptions with @throws in JavaDoc Consider whether to handle, propagate, or convert exceptions Would you like more details on any specific aspect of Java exceptions?  ( 3 min )

If you've worked with React or JavaScript modules, you might have noticed that sometimes you write imports with curly braces ({}) and sometimes without them. Ever wondered why? Let’s break it down. A default export allows a module to export a single value. It’s useful when your file exports just one main thing — like a component. // components/Footer.jsx export default function Footer() { return ...; } import Footer from './components/Footer'; 🚫 No curly braces needed for default exports. A named export allows you to export multiple values from a file. You must import them using curly braces. // components/Contact.tsx export function Contact() { ... } export function AnotherHelper() { ... } import { Contact } from './components/Contact'; ✅ Curly braces required for named exports. You can combine both in one file: export default function App() { ... } export function Helper() { ... } Then import like: import App, { Helper } from './App'; Hope this clears up the mystery behind those curly braces!

database server is a server which uses a database application that provides database services to other computer programs or to computers, as defined by the client–server model.[citation needed][1][2] Database management systems (DBMSs) frequently provide database-server functionality, and some database management systems (such as MySQL) rely exclusively on the client–server model for database access (while others, like SQLite, are meant for use as an embedded database). Users access a database server either through a "front end" running on the user's computer – which displays requested data – or through the "back end", which runs on the server and handles tasks such as data analysis and storage. In a master–slave model, database master servers are central and primary locations of data while database slave servers are synchronized backups of the master acting as proxies. Most database applications respond to a query language. Each database understands its query language and converts each submitted query to server-readable form and executes it to retrieve results. Examples of proprietary database applications include Oracle, IBM Db2, Informix, and Microsoft SQL Server. Examples of free software database applications include PostgreSQL; and under the GNU General Public Licence include Ingres and MySQL. Every server uses its own query logic and structure. The SQL (Structured Query Language) query language is more or less the same on all relational database applications. For clarification, a database server is simply a server that maintains services related to clients via database applications. DB-Engines lists over 300 DBMSs in its ranking.  ( 3 min )

A data mart is a structure/access pattern specific to data warehouse environments. The data mart is a subset of the data warehouse that focuses on a specific business line, department, subject area, or team.[1] Whereas data warehouses have an enterprise-wide depth, the information in data marts pertains to a single department. In some deployments, each department or business unit is considered the owner of its data mart, including all the hardware, software, and data.[2] This enables each department to isolate the use, manipulation, and development of their data. In other deployments where conformed dimensions are used, this business unit ownership will not hold true for shared dimensions like customer, product, etc. Warehouses and data marts are built because the information in the datab…  ( 4 min )

In recent years, the notion that “big data is dying” seems to be gaining traction. Some say the big data craze has faded, while others lament the shrinking job opportunities, the increasing complexity of platforms, and the growing intricacy of business demands. But does this really mean big data is dying? I don’t think so. In my view, what’s truly dying is not big data itself, but rather the outdated “dragon-slaying techniques” that no longer have any “dragons” to slay. The “dragon” has evolved, while our weapons remain stuck in the past. Technology needs to evolve, architectures need to be restructured, and capabilities need to be upgraded. To understand the current state and trends of big data, we must first examine how it has evolved step by step. The development of big data can be divi…  ( 8 min )

When you're building a dynamic frontend—like a game store, product listing, or job board—your UI needs to handle a lot of state: What page are we on? What filters are selected? Are we sorting by newest, most relevant, or trending? What platform, genre, or tags are selected? Managing all of that with separate useState hooks or deeply nested props can quickly become a nightmare. Enter the Query Object Pattern. A Query Object is a single JavaScript object that encapsulates all your query parameters—filter values, sort order, pagination, etc. const [query, setQuery] = useState({ genreId: null, platformId: null, sortOrder: 'relevance', searchText: '', page: 1, }); Instead of spreading your state across multiple hooks: const [genreId, setGenreId] = useState(null); const [platformId, s…  ( 4 min )

When learning programming or data structures, it’s easy to feel like we're making significant progress just by spending a lot of time coding or watching tutorials. We might think that by solving numerous problems or watching endless videos, we are improving our skills. However, after a certain point, we might find ourselves struggling to solve problems we’ve encountered before or feel stuck when faced with new challenges. This is the false sense of progress that many learners experience in their programming journey. At the beginning of learning programming, it’s common to feel like we are advancing rapidly. Solving coding problems and watching tutorials can give us the impression that we're progressing. But when it comes to solving more complex problems or applying what we've learned to re…  ( 5 min )

Limitations of Virtual Machines and Servers? 1. Startup & Shutdown Times: VMs generally take longer to start up and shut down compared to containers, which can impact the speed of deployment and scaling. This delay can be a bottleneck in environments requiring rapid provisioning and de-provisioning of resources. 2. Dynamic Resource Allocation is Complex: VMs rely on hypervisors(such as VMware ESXi, Microsoft Hyper-V) to manage and allocate resources like CPU, memory and storage. This adds complexity because the hypervisor needs to handle various resource demands and ensure fare distribution. (Earlier we would need to Shutdown the VM for changing the allocated resources but now this can be done on a running instance as well but it still needs input/human intervention and its complex) Aut…  ( 4 min )

message queues or event streaming platforms play a critical role in enabling this communication. But here's the key question: How reliably is a message delivered from sender to receiver? Let’s break down the three core delivery semantics you’ll encounter in real-world systems 👇 At-Most Once 🔹 Messages are delivered zero or one time No retries, so if something fails — the message is lost no guarantee of delivery 💡 Use case: Monitoring metrics, logs, or telemetry where occasional loss is acceptable. At-Least Once 🔹 Messages are never lost may be delivered multiple times deduplicate on the consumer side 💡 Use case: Order processing, notifications, analytics — where duplicates can be filtered or ignored. Exactly Once 🔹 Each message is delivered only once, no duplicates, no loss very hard to implement complexity, latency, and often performance trade-offs 💡 Use case: Financial transactions, trading systems, accounting — where idempotency is not supported and every operation must be precise. Choosing the right delivery guarantee isn’t just about tech — it’s about your use case and business priorities. a single duplicate message could cost thousands. 📌 Message Queue vs Event Streaming Platform? 🔹 Message Queues (like RabbitMQ, SQS): Focus on reliability and order for point-to-point communication. 🔹 Event Streaming Platforms (like Kafka, Pulsar): Optimized for broadcasting, storing, and replaying high-throughput event logs. Ideal for event-driven systems and real-time analytics. What’s your go-to strategy for delivery semantics in distributed systems? Let’s discuss in the comments 💬  ( 4 min )

Let’s be honest. You've spent hours wrangling with bloated WordPress themes or waiting on backend fixes just to launch a simple page. Sound familiar? It’s not you. It’s the traditional CMS model.

The landscape of frontend development is constantly evolving, especially when it comes to UI components. For years, we've juggled comprehensive libraries like Material UI, Ant Design, or Chakra UI. They offer a wealth of pre-built components, but often come with trade-offs: heavy bundle sizes, complex style overrides, and a feeling of being locked into their specific ecosystem and design opinions. Then came Shadcn/ui, and for many developers like myself, it fundamentally changed the game. Shadcn/ui isn't a component library in the traditional sense. It's better described as a curated collection of beautifully designed, highly reusable UI primitives and components built using Radix UI for behaviour and accessibility, and Tailwind CSS for styling.

Hello Dev.to community! 👋 As a developer, I often found myself repeating the same Git commands over and over again during my workflow... So I built a small CLI tool called gitNull to make that easier! gitNull? A lightweight GitFlow helper written in Node.js. It automates common git actions like: gitNull start-feature gitNull finish-feature gitNull push – adds, commits and pushes in one command With a retro CLI look and some colorful feedback thanks to chalk and figlet. I love clean workflows, and I always wished Git had something a bit more guided. I didn’t want a full GUI — just a faster terminal flow. This is my first attempt at building a CLI tool, and I'm sharing it to get feedback and ideas from the community. Check it out on GitHub: https://github.com/faithreborn/gitnull Whether you're a CLI junkie, a GitFlow user, or someone who just hates typing long commands — I’d really appreciate if you give it a try and tell me what you think. ❤️ Any feedback, issues or PRs are welcome!

Microsoft's Visual Studio Code, commonly just called VS Code, is a great piece of software. This is in no small part due to all extensions on the extensive marketplace providing extreme flexibility. It has proven it to be adaptable to most, if not all, software development projects. My editor of choice, neovim, provides no such benefits out of the box, requiring me to configure everything, install language plugins, code completion, myself. Vim and neovim are by far more powerful editors, but lacking the ease-of-use of VSCode, and easy discoverability of new features; I don't recommend beginners to use these. Configuration is done through code, not a nice UI allowing you to browse a marketplace and take popularity into consideration when choosing between different plugins for the same task…  ( 8 min )

Today we’ll create our first entity, learn how to create events, write a simple query to fetch all events, and of course, test everything to make sure it actually works. Let’s start with the basics. We’ll define our first entity, which is essentially just a SQL table. In it, we need to specify the field names and their types. The first entity will be called event. It will store all the core info about each event: the account of the user who created it, the question text, creation time, expiration time, a flag that shows whether the event is closed, and the result. I want to directly link each event to its creator’s account. For that, we’ll use the type ft4 account, which represents a user in the FT4 system. We import it from the FT4 library in oddly/module.rell like this: module; import l…  ( 8 min )

When using gRPC, one of its biggest advantages over traditional REST is the use of a single long-lived connection over HTTP/2. What does that mean? Unlike REST where every request opens a new connection, gRPC establishes one persistent connection between the client and the server. Through this connection, multiple messages can be exchanged — in both directions — without reopening it each time. Think of it like this: Imagine going to a restaurant. With REST, you’d have to enter and exit the restaurant every time you wanted to order something new. But with gRPC, you sit down once, and continue to place multiple orders and have conversations — all through that single session. Benefits of gRPC’s Long-Lived Connection: ✅ Reduced latency ✅ Real-time communication ✅ Efficient use of resources ✅ Bidirectional streaming supported Use Cases: Perfect for real-time apps like online games, chat systems, IoT devices, and microservice communications — where speed and efficiency matter most.  ( 3 min )

Introduction The concept of sequence modeling is fundamental to understanding RNNs. Many real-world problems involve sequences, where the order of elements carries significant meaning. For example, in language, the meaning of a sentence depends heavily on the order of the words. Similarly, in video analysis, the sequence of frames determines the action being performed. RNNs excel at capturing these dependencies, making them a powerful tool for a wide range of applications. The application of RNNs is prevalent in the field of deep learning. The history of RNNs is marked by continuous evolution. Early RNN architectures faced challenges like the vanishing gradient problem, which hindered their ability to learn long-range dependencies. However, innovations like Long Short-Term Memory (LSTM) …  ( 7 min )

What If You Could Feel Data? This amazing idea is becoming real through something called synesthetic data interfaces. That’s a big name, but it simply means using your senses—like hearing, sight, or touch—to understand data. It’s like turning code or information into a song, a rainbow, or even a feeling in your hand. Why is this important? Because everyone learns differently. Some people understand pictures better, while others learn better by hearing or touching things. Synesthetic data interfaces help people understand hard things in their own way. And guess what?

After a frustrating day dealing with a broken pipeline at work, all I wanted was to relax with a good story on Wattpad. 😌 I opened the app on my phone, and something strange happened. The home page loaded fine, but when I tried to open any story, I got stuck on an endless loading screen. At first, I thought it was temporary maintenance. But after a week of the same issue, I knew something else was wrong. I did some digging on Reddit and found a pattern: Only Jio users in India were having this problem 🇮🇳 The Wattpad home screen would load, but stories wouldn't People using other networks like Airtel had no issues I tested this by connecting to my Airtel hotspot instead of my Jio data, and suddenly Wattpad worked perfectly!

Sick of flaky integration tests? You run your tests once — they pass. Run them again — they fail. Maybe the third-party API timed out. Or the response changed. Or your internet blinked. Integration tests should give you confidence, not stress. That’s where deterministic integration testing comes in. Imagine recording your API interactions once and replaying them forever — offline, fast, and predictable. No network. No surprises. That’s exactly what Vcr.HttpRecorder does. It’s inspired by the original Ruby VCR gem, revived for .NET and brought back to life with new features and bug fixes in my fork. In traditional integration tests, you call real services — maybe a payment gateway, an external API, or even another microservice. But real services are unpredictable: They might be slow or d…  ( 5 min )

Overview, Historical Timeline, Problems & Solutions When you write Python code, you use symbols to separate, group, or define parts of the program. These symbols are called delimiters. A delimiter does not perform an action like an operator. Instead, it marks structure and boundaries. In writing, you use punctuation to make ideas clear. A comma breaks up items. A period ends a sentence. In Python, delimiters help the interpreter make sense of what comes next. Python uses delimiters to shape the structure of your code. (1 + 2) * 3 ['a', 'b', 'c'] {"key": "value"} x = 7 def f(): pass You use delimiters to build lists, assign values, pass arguments, and group code. Python requires these markers so it can read your program correctly. When you write a list, call a function, or create a diction…  ( 6 min )

This is a submission for the Permit.io Authorization Challenge: Permissions Redefined I built a Web3-based CMS (Content Management System) designed for managing decentralized content like collections, banners, presale campaigns, and other on-chain/off-chain data. The CMS provides an admin dashboard where team members can log in using their crypto wallets and manage the platform’s content in a more structured and user-friendly way. The key problem it solves is the lack of permission control in many Web3 tools. Typically, dApps allow wallet login but don’t differentiate between users. In my CMS, I introduced fine-grained access control so that different roles (e.g., admin, content editor, viewer/analyst) have access only to the features relevant to them.

jienweng.com Hi all. I recently rebuilt my personal site using 11ty, and I wanted to share a bit about why I chose simplicity over flashy design. Like many developers, I started with a more complex stack — Astro, React, lots of moving parts. It looked cool, but it started to feel like I was building for the tools instead of myself. So I started over with 11ty. It’s fast, flexible, and just lets me focus on content. Tbh I hate npm, and with 11ty i like that there's no bundlers, no frameworks. Just clean HTML, Markdown, and a bit of templating. The site is still a work in progress, but I like how it feels now — more personal, less performative. It’s a place for my notes, thoughts, and projects. Nothing fancy. Just mine. Would love any feedback or thoughts — especially from others who’ve simplified their stacks or gone the “digital garden” route. Thanks for reading!  ( 3 min )

Authentication is at the heart of every secure web application. As frontend developers, understanding modern authentication flows and how to implement them securely is crucial. This article explores the most widely used authentication methods today: OAuth 2.0, JWT (JSON Web Tokens), and OpenID Connect, and introduces some emerging approaches. Authentication determines who the user is, and authorization determines what they can access. An insecure authentication mechanism can expose your app to session hijacking, data leaks, and impersonation attacks. Modern SPAs (Single Page Applications) demand decoupled and secure authentication techniques that work well across multiple clients, including web, mobile, and APIs. OAuth 2.0 is an authorization framework, not an authentication protocol by it…  ( 4 min )

Introduction When working with SQL, especially with outer joins, it's crucial to understand how to filter your results effectively. In your case, you're looking to perform a right outer join between two tables and then conditionally include or exclude rows based on the status from one of these tables. This article will break down how to efficiently filter results using outer joins in SQL while ensuring you get data according to specific conditions. Understanding the Outer Join Behavior Outer joins, particularly the right outer join you mentioned, are designed to include all the entries from the right table (in this case, table2), along with matching rows from the left table (table1). If there are no matches, SQL will return NULL for columns from table1. This behavior poses a challenge when…  ( 4 min )

Pack your bags up the day before. Make sure to get the basics, underwear, socks, toothbrush, medications, pjs, travel documents, license, passport, – don't get deported, little gifts, etc... 'etc...'? This etcetera is the other stuff you forget and will inevitably have to purchase at your destination. Yes, I account for this because sometimes it doesn't matter how much time ahead I pack there is usually something I missed packing and have to either bother a relative to let me borrow it. I don't love forgetting stuff but at this point I rather forget than having to change my ways, like packing weeks before like my mother does. Smart lady, never forgets anything. I'm more like my dad in these type of things. 'Men'. I'm not sure if it's a fair thing to asume, 'all men are bad at packing' but I tell you, there is a pattern. My male cousin, doesn't travel, I wonder if he would also suck at packing. I think having a comfortable amount of money makes you care less because you can just purchase what you forget at the place where you go to maybe, – saying this in the most possibly humble way. For example, I forgot to pack belts, now I have to go to a store and buy something I already had for free at home.  ( 3 min )

A lightweight RabbitMQ framework for Node.js, built to eliminate boilerplate and let you focus on business logic. Let’s say you’re building an app with several moving parts—maybe one service processes user signups, another sends welcome emails, and another tracks analytics. Normally, these services would need to talk to each other directly and immediately—which makes things tightly connected and harder to scale. Messaging and event-driven architecture solve this by letting each part send and receive information independently. It works like this: When something important happens (like a new user signing up), that part of the app sends a message—think of it like dropping a letter in a mailbox. RabbitMQ. Here’s a simple example: A user signs up → The app sends a user.created message → The > e…  ( 6 min )

“Summon a daily contribution. Maintain the illusion. Worship the green.” You ever stare at your GitHub contribution graph like it's a Tamagotchi you forgot to feed? Yeah, me too. So I built something unholy: A Bash-based automation daemon that ensures your GitHub profile always looks... alive. It commits. It pushes. It even wakes your computer from the dead to do it. ⏰ Schedules fake-but-believable commits at randomized human hours 🔁 Retries if GitHub rejects your offering 💾 Logs your ritual attempts and successes 🌴 Vacation mode, so your ritual pauses when you need rest (or alibis) 🔥 Self-healing if a ritual was missed (triggered by guilt and grep) 👁️ macOS popup warnings like: > “⚠️ No ritual detected today. The square is empty. You are exposed.” 🧙 Choose your commit incantations like: feat: added function nobody asked for fix: removed existential crisis from variable name 📜 Add custom altar messages 🔓 Unlock rare achievements like: "100 Days of Devotion" "The Sacred Streak" ✅ Daily ritual cron + safety check daemon 🪞 GitHub visibility flip (goes public, commits, hides again) 🧙‍♀️ Bash installer with prompt-based setup 🏕️ Vacation flag toggle for burnout mercy 🧾 .command launcher for double-click ritualism 🎨 Coming Soon: SVG badges GitHub profile theme pack Guilt Daemon™ (shames you in Slack when your squares go dark) Yes. I built it for fun. I also use it daily. It’s part spiritual theater, part productivity placebo, and part real automation. Bash cron, pmset, at, and osascript (macOS) GitHub CLI (gh) Dark magic I'm testing the waters. If enough devs want this, I’ll clean it up, ship a proper version, maybe even add a front-end GUI (Tauri? React? Electron? We’ll see).

This is going to be a quick Devlog, because I just want to get back to this issue I'm having and figure out a solution for it. I've gone back to the drawing board, trying to figure out how to effectively unwrap the donut-shaped Voronoi diagram I have for my river tiles. I think this is the third week I've been working on the same problem now, so I'm getting a little frustrated because 3 weeks is a lot of time that could have been spent working on some other part of the game. I just feel like when I do solve this, one - I won't have to think about it again, and two - the visual pay-off will have been worth it. I also feel like I've invested too much time to not get some kind of pay-off for this feature. The biggest issue that I'm having is that when I have the shapes aligned as they leave one of the corner tiles and enter the straight tile, by the time they flow along the straight path in time to reach the bottom, they're not quite aligned. Now I think the problem I'm having is that I've got a slight overlap on the tiles, the row beneath covers the row above by a couple of pixels - enough to make the borders around the tiles match up. This looks fine in practice, but I need to compensate for that when aligning the shapes, and I feel like this is throwing a spanner in the works. So, I'm redoing my hex grid, and I'm using this article as a reference... https://www.redblobgames.com/grids/hexagons/ I'm going to try and math my way through this tonight. Wish me luck! Cheers, Dan.  ( 3 min )

This article will introduce how to quickly import csv or txt files larger than 1g into the database. Here, we prepared a CSV file with 10 million rows x 30 columns x 4GB. At first, I tried to import it with Navicat. The first problem I encountered was that the encoding format was unknown, which led to many attempts to find the correct encoding. The second problem is that Navicat reads and writes one by one. Although this does not take up memory, the speed is very slow. The third problem is that halfway through the import, an error was reported because the field length was not enough! ! ! I had to reset the field length and import from 0 again. . . What's worse is that after setting one field, another error was reported. . . Now, we use the DiLu Converter Import tool to solve these problems one by one. Encoding: It can be automatically identified by default (for files with unknown encoding). If the encoding format of the file is known, you can select or enter its encoding format to speed up the parsing speed. Chunk Size: You can set the number of rows to import at a time according to the available memory of your computer. My computer has a total of 16G memory, about 9G is available, and 500,000 is set in a batch. Here, you must set the size according to the available memory. If the setting is too large, the memory may overflow, and if the setting is too small, it will not speed up. And The just click start You can see that it takes about 20 seconds to import a batch of 500,000 rows, and the memory usage is less than 1G Finally, it took about 5 minutes to import this csv file of 10 million rows x 30 columns x 4GB, and the maximum memory usage was about 1G. Because the tool imports files in batches according to batch size, no matter it is 1 file or hundreds or thousands of files, no matter a single file is 1G or 100G, as long as the batch size is set reasonably, it can be imported quickly, stably and without consuming memory.  ( 4 min )

Creating generic structures in Rust can initially seem challenging, especially when it comes to default types. In this article, we will explore how to create a generic structure with a default type, allowing users to omit the generic parameter when defining instances. We’ll investigate why the Rust compiler requires explicit type annotations in certain situations and provide a step-by-step solution to this common problem. Why Does Rust Require Explicit Type Annotation? Rust is a statically typed language, which means types are known at compile time. When you define a generic structure, the compiler often needs to understand what specific type to use for the generics. In your code example, you're trying to instantiate C without specifying its type, which results in the following error: erro…  ( 4 min )

If you’ve ever played with dominoes, you know that the order of the numbers doesn’t matter—[1,2] is the same as [2,1]. That's the central idea behind this popular LeetCode problem: 💡 Given a list of dominoes, return how many pairs of dominoes are equivalent. Two dominoes [a, b] and [c, d] are equivalent if: (a == c and b == d) or (a == d and b == c) Let's dive into the most optimal way to solve this! Instead of comparing every pair (which would take O(n²) time), we can: Normalize each domino: [a, b] becomes [min(a, b), max(a, b)] Use a hash map to count how many times each normalized domino appears. Every time we see a duplicate, we count how many previous identical dominoes we've seen. Add that count to the result (because every new domino can pair with all previous identical ones).

OpenSearch, a powerful distributed search and analytics engine, offers high scalability and near real-time search capabilities. However, as data volume and query complexity grow, performance bottlenecks often emerge—particularly around indices and shards. This guide breaks down actionable strategies to optimize indexing, querying, and shard management for improved performance and cluster health. Index: A logical namespace that maps to one or more physical shards. Shard: A basic unit of storage and search in OpenSearch. Each shard is a Lucene index. Performance is tightly tied to how indices and shards are structured, distributed, and queried. Too many shards create overhead; too few limit concurrency. Aim for ideal shard sizes between 10–50 GB. Avoid the default 5 shards unless justified. …  ( 4 min )

PBCs are for-profit companies that are legally obligated to prioritize a social mission alongside the interests of shareholders. The plans mark a reversal for OpenAI, which had previously floated a for-profit conversion involving spinning out the nonprofit entity. “OpenAI was founded as a nonprofit, and is today overseen and controlled by that nonprofit. Going forward, it will continue to be overseen and controlled by that nonprofit,” the ChatGPT-maker said.  This can be done without…

The Securities and Exchange Commission’s (SEC) enforcement approach on crypto firms has left a lasting “regulatory overhang” within the industry, according to Devin Finzer, co-founder and CEO of OpenSea.  Speaking to Cointelegraph, Finzer said that during Biden's administration the agency unfairly targeted good actors in the crypto space, including OpenSea. “There's all sorts of digital assets, you know, you shouldn't treat them all the same. That's obvious. But I think the approach that the prior SEC was taking was kind of this, you know, very, very generic.” The SEC issued a Wells notice — a formal notification that is often a precursor to enforcement action — to OpenSea in 2024, alleging that the NFT marketplace was operating as an exchange for unregistered securities. At the time, Finz…

US President Donald Trump’s crypto businesses are drawing increased scrutiny on Capitol Hill and beginning to influence the progress of US digital asset legislation. As Republican lawmakers in the US House of Representatives unveiled their draft of a digital asset market structure bill on May 5, Democrats prepared for a united response to Donald Trump’s deepening connections with the industry. Speaking to Cointelegraph on May 5, a Democratic staffer with knowledge of the matter said that House Financial Services Committee Ranking Member Maxine Waters planned to lead some members of her party out of a Republican-led hearing discussing digital assets. The May 6 hearing, entitled “American Innovation and the Future of Digital Assets” and led by Committee Chair French Hill, could address draft…

Bitcoin’s (BTC) price has dropped by 4.3% in the last three days after nearly reaching $97,900 on May 2.

The United States Department of the Treasury has sanctioned a Myanmar militia group known as the Karen National Army (KNA), accusing it of crypto-related scams and other criminal activities. According to a May 5 press release issued by the agency, the Karen National Army has been orchestrating a variety of crypto scams, including the infamous “pig butchering” scam, which lures victims into contributing more and more to fake crypto schemes. Americans “have collectively lost billions of dollars” from scams such as those emanating from Myanmar, the release reads, without specifying an amount. “Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned the Karen National Army (KNA), a militia group in Burma, as a transnational criminal organization, along …

Asset manager VanEck has asked US regulators for permission to list an exchange-traded fund (ETF) holding BNB, the native token of Binance’s BNB Chain, regulatory filings show.  The ETF is designed to accumulate spot BNB (BNB) tokens and “may, from time to time, stake a portion of the [fund’s] assets through one or more trusted staking providers,” according to the ETF’s S-1 prospectus. The filing marks the first time an asset manager has filed for a BNB ETF in the United States. The BNB token has a market capitalization of roughly $84 billion, according to data from CoinMarketCap.

Crypto users are weighing in as Alex Mashinsky, the former CEO of Celsius Network, prepares to stand before a judge on May 8 to face sentencing for commodities fraud and a fraudulent scheme to manipulate the price of the platform’s token. In a May 2 filing in the US District Court for the Southern District of New York (SDNY), prosecutors released several impact statements from individuals affected by the collapse of Celsius filed after the initial deadline. Though at least one suggested clemency for the former CEO, many told the court about the financial and personal losses caused by the crypto firm filing for bankruptcy, and hinted that Mashinsky should be held accountable for misrepresenting the company. “Many of the people who participated in this fraud, benefited from this fraud, and p…

Key points: Bitcoin is witnessing a tough battle between the bulls and the bears at the $95,000 level. Solid buying by spot Bitcoin ETF investors last week signals a positive shift in investor sentiment.  Select altcoins have held their support levels, increasing the likelihood of a short-term up move. Bitcoin (BTC) slipped below the breakout level of $95,000 on May 4, indicating profit booking at higher levels. The bulls tried to push the price back above $95,000 on May 5 but are facing stiff resistance from the bears.  Glassnode senior researcher CryptoVizArt said in a post on X that Bitcoin maintaining above $93,000 was very surprising and also risky as the rally to the $93,000 to $96,000 range “pushed the profit-taking volume above the statistical levels.” CryptoVizArt added that t…

Key Takeaways: 88% of Bitcoin’s supply is in profit below $95,000, indicating a reset in investor expectations. The current price range of $75,000–$95,000 may represent a structural bottom, aligning with market conditions from Q3 2024. The Market Value to Realized Value (MVRV) Ratio at 1.74 acts as a historical support zone, signaling cooling unrealized gains and potential for future growth. Bitcoin’s (BTC) market dynamics are shifting, as Glassnode data reveals that 88% of the supply is currently in profit, with losses concentrated among buyers in the $95,000-$100,000 range.

Key takeaways: Bitcoin has historically outperformed gold, more recently by sixfold. Gold’s climb toward $5,000 could set the stage for significant Bitcoin gains. Weakening US dollar and rising global liquidity remain key drivers for both assets. Gold’s march toward $5,000 per ounce and beyond has become a big topic among hard-asset bulls, including Yardeni Research’s head Ed Yardeni and billionaire investor John Paulson. But what could happen to the price of Bitcoin (BTC), touted as “digital gold” by many, if the precious metal surges even higher? BTC price jumped 6x last time gold rallied Bitcoin has historically delivered far more substantial gains than gold when their markets rally concurrently. From March 2020 to March 2022, during the Federal Reserve’s ultra-loose monetary …

Opinion by: Tracy Jin, Chief Operating Officer, MEXC Market manipulation is everywhere and yet nowhere to be seen. It is an invisible threat affecting crypto and traditional markets, leaving ordinary traders counting the costs. Sometimes, manipulation is obvious — illiquid tokens being pumped high before being dumped just as fast — but often, it's subtler and more challenging to detect. What's more concerning is that these schemes are no longer the domain of rogue whales or amateur pump groups. Signs increasingly point to highly organized, well-funded networks coordinating activities across centralized exchanges, derivatives platforms, and onchain ecosystems. As these actors grow in sophistication, their threat to market integrity expands exponentially. A tale as old as time  Market manipu…

Ripple, the US-based crypto services firm behind the XRP Ledger, has committed $25 million in Ripple USD (RLUSD) to education nonprofits DonorsChoose and Teach For America. According to a May 5 announcement, the grant will be processed through the crypto charity intermediary service The Giving Block. DonorsChoose CEO Alix Guerrier said "teachers are going the extra mile for their students' education, even spending hundreds — sometimes thousands — of dollars out-of-pocket for their classrooms." The donations are meant to provide teachers with resources for such initiatives. Ripple cites a 2024 Gallup survey showing that 55% of US parents and adults are dissatisfied with the quality of K-12 education in the United States. This highlights “constraints and gaps in funding for education,” the reports reads. Ripple CEO Brad Garlinghouse said in the statement: “We hope to inspire others to do the same, starting with Teacher Appreciation Week, and leading into the rest of the year to support students and teachers with the resources they need to build a stronger future for themselves and their communities.” Teach For America CEO Aneesh Sohoni said the new funding will allow the organization to expand its “Ignite Tutoring Fellows program, drive innovation in our Reinvention Lab, and provide crucial financial assistance” to prepare teachers.

Last month, Binance co-founder Changpeng “CZ” Zhao pledged over half a million dollars worth of crypto to the earthquake disaster relief effort in Thailand and Myanmar.

$243M Bitcoin scam that led to kidnapping and chaos In one of the most bizarre crossovers between digital crime and real-world violence, a group of young cybercriminals stole almost $243 million in Bitcoin (BTC). Within weeks, the fallout spilled from the blockchain into a quiet Connecticut suburb, ending in a harrowing kidnapping plot. If this seems like the plot of a Netflix thriller, you’re not alone in thinking that. But it happened. And fast. Let’s unpack how a Minecraft-playing teenager, an underground network of crypto thieves and a Lamborghini-driving suburban couple all became tangled in a wild web of digital deception and real-world chaos. It all started when a Washington, D.C.-based cryptocurrency investor received a suspicious phone cal…

US President Donald Trump will host a gala dinner for top holders of his Official Trump (TRUMP) memecoin despite bipartisan criticism and renewed calls for impeachment. In a May 5 Truth Social post, Trump announced that he will hold a gala dinner with major TRUMP holders on May 22. The announcement follows multiple US lawmakers expressing concern over the initiative. In late April, Massachusetts Senator Elizabeth Warren called on government officials to address questions related to Trump’s memecoin and his media company. Controversies grew after Trump announced a dinner and White House tour for some holders of his TRUMP memecoin. “President Trump’s announcement promises exclusive access to the presidency in exchange for significant investment in one of the President’s business ventures,” a…

Binance co-founder Changpeng “CZ” Zhao has proposed Bitcoin and BNB as the first digital assets to build Kyrgyzstan’s national crypto reserves. On May 5, Zhao shared on X that he had advised Kyrgyzstan to start with Bitcoin (BTC) and BNB (BNB) when building its national crypto reserve. In 2024, Forbes claimed that Zhao holds about 94 million BNB tokens, or 64% of BNB’s circulating supply. At the time of writing, these tokens are worth about $55 billion.  The proposal followed Zhao’s earlier announcement that he had begun advising Kyrgyzstan’s National Investment Agency (NIA) on blockchain and crypto-related matters. On April 3, Zhao confirmed he’s been officially and unofficially advising governments on crypto frameworks and blockchain solutions. The former Binance CEO said that he finds…

Key takeaways: XRP forms a bearish descending triangle on the daily chart, risking a 45% drop to $1.20. Declining daily active addresses signal reduced transaction activity and liquidity. A breakout above $2.18 could invalidate the bearish pattern. The XRP (XRP) price flashes warning signs as a bearish technical pattern emerges on its daily chart, coinciding with declining network activity.  XRP descending triangle hints at 45% price drop The XRP price chart has been forming a descending triangle pattern on its daily chart since its late 2024 rally, characterized by a flat support level and a downward-sloping resistance line.

While many crypto ecosystems focus on decentralization as the core tenet of Web3, Aptos is seeing success with hybrid platforms that blend Web2 and Web3 technologies, commonly referred to as “Web2.5.” In an interview at the Token20249 event in Dubai, Aptos’ head of ecosystem, Ash Pampati, told Cointelegraph that they see Web2.5 platforms earn “tons of revenue” within Aptos. He noted that consumer-focused applications in particular are thriving on the network. Web2.5 is a term used to describe a combination of Web2 and Web3 technologies. The term describes platforms or applications that blend centralized Web2 experiences with decentralized Web3 elements.  These applications often avoid full decentralization, drawing criticism for not fully embracing the Web3 vision.

Ethereum co-founder Vitalik Buterin has explained when he believes rollup-based layer-2 platforms should go decentralized, and why “as soon as possible” is not the correct answer. In a May 5 X post, Buterin explained that there is a right time for rollup-based scalability solutions to transition to a decentralized model. This moment depends on how low the proof system’s failure probability has fallen compared with the risks introduced by centralization. Buterin’s thread came in response to a separate post by decentralized exchange Loopring founder and CEO Daniel Wang. Wang explained in his thread that the maturity of a system matters to its security: “Not all code is created equal. A rollup can be Stage 2, but running fresh code that’s never been tested under real stress.“ Rollup developme…

Opinion by: Shane Molidor, Founder, Forgd For years, launching a crypto project in the United States has been a maze of uncertainty. Legal ambiguity and a hostile regulatory environment have driven founders offshore, turning places like Switzerland and the Cayman Islands into global hubs for blockchain innovation.  With Trump’s election, things finally started to change, with a US administration openly declaring its intention to be crypto-friendly. Yet, despite the rhetoric, nothing concrete has changed so far. Launching a crypto project in the US is just as difficult as ever. US regulatory agencies continue to offer nothing but vague threats and “regulation by enforcement” lawsuits. America wants to be a leader in crypto, but, even under the Trump administration, it isn’t taking action to…

What is a digital twin? A digital twin is a virtual model or replica of a physical object, system or process. It’s like a digital mirror, allowing us to simulate, monitor and predict the behavior of real-world entities in real-time.  These virtual counterparts are designed to pull data from physical sensors or inputs, providing a continuous feedback loop that helps with analysis, optimization and decision-making. Digital twins can represent almost anything, from machinery in a manufacturing plant to human behavior or entire cities. In industries like healthcare, automotive, manufacturing and urban planning, digital twins allow for better resource management, predictive maintenance and more accurate simulations before physical changes are made. In e…

US President Donald Trump gave clashing answers to whether he has profited from the crypto memecoin he launched in January, just days before he re-entered the White House. In a wide-ranging interview with Kristen Welker on NBC News’ Meet the Press released on May 4, Trump said he was “not profiting from anything” when asked to respond to critics who said he’s profiting from the presidency through the memecoin. “So you’re not profiting off of the cryptocurrency at all?” Welker asked Trump. “I haven’t even looked,” Trump admitted. “But I’ll tell you what. Look, if I own stock in something and I do a good job, and the stock market goes up, I guess I’m profiting.” Trump launched his memecoin, Official Trump (TRUMP), on Jan. 17, which hit a peak of $73.43 two days later, just a day before he wa…

OpenAI says it ignored the concerns of its expert testers when it rolled out an update to its flagship ChatGPT artificial intelligence model that made it excessively agreeable. The company released an update to its GPT‑4o model on April 25 that made it “noticeably more sycophantic,” which it then rolled back three days later due to safety concerns, OpenAI said in a May 2 postmortem blog post. The ChatGPT maker said its new models undergo safety and behavior checks, and its “internal experts spend significant time interacting with each new model before launch,” meant to catch issues missed by other tests. During the latest model’s review process before it went public, OpenAI said that “some expert testers had indicated that the model’s behavior ‘felt’ slightly off” but decided to launch “du…

Malicious actors appear to have infiltrated the New York Post’s X account in an attempt to scam crypto users on the microblogging platform.  Some X users from the crypto community have recently reported having received a private message from the New York Post’s X account inviting them to feature in a podcast and to contact them via Telegram.  The spurious messages were first discovered on May 3 by Kerberus founder and CEO Alex Katz, who shared a screenshot of a message made out to be from author and journalist Paul Sperry via the official nypost account.  “What’s interesting about this case is that the scammer gained unauthorized access but didn’t post a Pump.fun address or wallet drainer.

Key points: Bitcoin’s positive sentiment should remain intact if BTC price stays above the 20-day EMA near $92,000. Several altcoins show bullish chart patterns in the 4-hour and 1-day timeframes. Bitcoin (BTC) has given back some of the gains over the weekend, and the price has pulled back to the breakout level of $95,000. Buyers will have to successfully hold the $95,000 level to keep the bullish momentum intact. Bitcoin network economist Timothy Peterson said in a post on X that Bitcoin could surge to a new all-time high and reach a target of $135,000 in the next 100 days if certain conditions are met. Peterson believes a drop in the CBOE Volatility Index below 18 could trigger a “risk-on environment” favoring Bitcoin. The other crucial points needed for the Bitcoin rally are a fall …
